Overview
The world's first .NET & Unity client for Holochain.
This library will allow you to connect any .NET or Unity client to Holochain and enjoy the power of a fully de-centralised distributed P2P multi-network agent-centric architecture.
This will help massively turbo charge the holochain ecosystem by opening it up to the massive .NET and Unity communities and open up many more possibilities of the things that can be built on top of Holochain. You can build almost anything you can imagine with .NET and/or Unity from websites, desktop apps, smartphone apps, services, AAA Games and lots more! They can target every device and platform out there from XBox, PS4, Wii, PC, Linux, Mac, iOS, Android, Windows Phone, iPad, Tablets, SmartTV, VR/AR/XR, MagicLeap, etc
We are a BIG fan of Holochain and are very passionate about it and see a BIG future for it! We feel this is the gateway to taking Holochain mainstream! 😉
There are two versions of HoloNET:
NextGenSoftware.Holochain.HoloNET.Client - Lightweight version that does not come with the holochain binaries (hc.exe and holochain.exe).
NextGenSoftware.Holochain.HoloNET.Client.Embedded - This version comes with the holochain binaries (hc.exe and holochain.exe) integrated.
You can also find the Test Harness here:
NextGenSoftware.Holochain.HoloNET.Client.TestHarness
Read more on how to use the Test Harness here.
As of v3.0.0 there are now a number of addon packages for HoloNET:
NextGenSoftware.Holochain.HoloNET.ORM The new HoloNET ORM (Object Relational Mapping) allowing very easy & rapid development of hApps. This consists of the HoloNETEntryBase, HoloNETAuditEntryBase, HoloNETCollection and HoloNETObservsableCollection classes. The first two can be extended to create your HoloNET Entry models that map directly onto your data structs in your rust hApp zome code. The second two are collections of these entries. You can then simply call basic CRUD methods on your classes such as Load, Save, Delete, etc making it very quick and easy to build hApps without having to worry about the lower complexities of Holochain or configure and use the Holochain Conductor or API's. You also get change tracking, version control & rollback functionality for free. HoloNET ORM allows any existing .net app/website/game/service to be rapidly and quickly converted to a Holochain hApp with very little code changes (you can simply add a new attribute to the properties in your models) and it will now map to your rust hApp structs (which WEB5 NextGenSoftware.OASIS.STAR) can also dynamically generate (it generates rust and c# code). More documentation will be coming soon for this...
NextGenSoftware.Holochain.HoloNET.ORM.Embedded This is exactly the same as above except it is using the embedded version of the HoloNET Client so it is integrated with the Holochain Conductor binaries.
NextGenSoftware.Holochain.HoloNET.Manager The new UI to HoloNET Client & HoloNET ORM show casing all of their advanced features. This has many generic backend and UI components that can be used to allow other .net devs to rapidly construct their own .net hApps using HoloNET HDK (HoloNET Client, HoloNET ORM, HoloNET Manager, WEB5 STAR ODK/HDK & HoloNET HyperNET). The HoloNET Manager is currently implemented in WPF but we have plans to port this to Uno, MAUI & OpenSilver meaning it can run natively on Windows, Mac, Linux, TV's, IPads, tablets, android, IOS & web. The work for this has already begun so expect future releases soon...
NextGenSoftware.Holochain.HoloNET.Manager.Embedded This is exactly the same as above except it is using the embedded version of the HoloNET Client so it is integrated with the Holochain Conductor binaries.
NextGenSoftware.Holochain.HoloNET.HDK The new HoloNET HDK consisting of HoloNET Client, HoloNET ORM, HoloNET Manager, WEB5 STAR ODK/HDK & HoloNET HyperNET. This package contains a plugin to the generic WEB5 STAR ODK No/Low Code Generator extending it so it can generate hApps from metadata built on top of the HoloNET Client/ORM. Release Coming Soon...
NextGenSoftware.Holochain.HoloNET.HDK.Embedded This is exactly the same as above except it is using the embedded version of the HoloNET Client so it is integrated with the Holochain Conductor binaries.
NextGenSoftware.OASIS.STAR The new No/Low Code Generator allowing you to generate code for any supported OASIS Provider (web2 and web3) and currently supports Holochain, IPFS, Solana, EOS, Ethereum, Telos, SEEDS, MongoDB, SQLLite, Neo4j & Azure. The generated code runs on top of OASIS/STAR COSMIC ORM making it a very easy and powerful way to share data between any web2 or web3 provider. Release Coming Soon...
NextGenSoftware.Holochain.HoloNET.HyperNET This is built on top of the HoloNET Client & HoloNET ORM and allows Unity and Unreal games to implement lag free P2P networking allowing near unlimited number of players to play online smashing previous limitations on classic cloud/server hosting. Release Coming Soon...
NextGenSoftware.Holochain.HoloNET.HyperNET.Embedded This is exactly the same as above except it is using the embedded version of the HoloNET Client so it is integrated with the Holochain Conductor binaries.
The latest release notes can be found below:
This release is a MAJOR release and milestone, HoloNET has been re-written from the ground up with many improvements, bug fixes etc. Part of this includes making it compatible with the latest beta version of Holochain. It has also been upgraded to work with the latest version of .NET (v8.0) so has even further performance improvements, bug fixes, etc.
This release also features the new HoloNET ORM (Object Relational Maping) package. This consists of the HoloNETEntryBase, HoloNETAuditEntryBase, HoloNETCollection and HoloNETObservsableCollection classes. The first two can be extended to create your HoloNET Entry models that map directly onto your data structs in your rust hApp zome code. The second two are collections of these entries. You can then simply call basic CRUD methods on your classes such as Load, Save, Delete, etc making it very quick and easy to build hApps without having to worry about the lower complexities of Holochain or configure and use the Holochain Conductor or API's. You also get change tracking, version control & rollback functionality for free. More documentation will be coming soon for this...
HoloNET ORM allows any existing .net app/website/game/service to be rapidly and quickly converted to a Holochain hApp with very little code changes (you can simply add a new attribute to the properties in your models) and it will now map to your rust hApp structs (which WEB5 STAR ODK/HDK) can also dynamically generate (it generates rust and c# code). Your hAPP will also be metaverse ready because STAR is also a interoperable metaverse generator (hence the name! 😉 ) and can also connect & bridge to any web2 or web3 provider thanks to it being built on the WEB4 OASIS API.
This release also features a new HoloNET Manager UI (think Launcher/Dev Store for .net and then some!) which show cases all of the advanced features of HoloNET Client and HoloNET ORM. This has many generic backend and UI components that can be used to allow other .net devs to rapidly construct their own .net hApps using HoloNET HDK. Yes, that is right, this client has grown so much now that it is now in a number of packages forming the official Holochain .NET HDK. This includes the WEB5 STAR ODK/HDK No/Low Code Generator allowing you to generate hApps built on top of the HoloNET Client and HoloNET ORM from simple metadata (this part is in alpha and will be shortly released). The HoloNET Manager is currently implemented in WPF but we have plans to port this to Uno, MAUI & OpenSilver meaning it can run natively on Windows, Mac, Linux, TV's, IPads, tablets, android, IOS & web. The work for this has already begun so expect future releases soon...
This release now fully implements the full Holochain Conductor Admin API so is now on par with the javascript and rust clients.
Finally this release also features HoloNET HyperNET allowing Unity and Unreal games to implement lag free P2P networking with near unlimited number of players to play online smashing previous limitations on classic cloud/server hosting.
This is the BIGGEST update to HoloNET to date and is pretty much a whole new product now! 😉
NOTE: The documentation is still for the previous version, please bare with us while we update this soon... thank you!
Read more here: https://github.com/holochain-open-dev/holochain-client-csharp/releases/tag/v3.0.0
This also now includes a msi installer for the HoloNET Manager so is the first real world deployment of HolonNET! Yay! 😃 This is a MAJOR milestone and shows and proves HoloNET working in a real world use case so you can give it a go yourself and give us vital feedback, thank you! 😃
This is the UI to HoloNET and is also used to demo and test all functionality of HoloNET Client and HoloNET ORM. Read more about this above.
Please leave feedback in our Telegram group. We are aware of a few bugs we are still working on, we originally wanted to wait till we got these fixed but if we are being honest we couldn't wait any longer to get this out there to get early feedback and see where the demands were for further features, enhancements and what part of the HoloNET Family we should focus more on etc...
We also wanted help squishing these last few bugs because they have been quite tricky little buggers to track down! Please find them in our GitHub Issues... 😃
Any other help would also be greatly appreciated, we are always looking for devs (and non devs) to join us on this exciting journey to the stars... We would love to hear from you! Thank you! 😃
HoloNET Code Has Migrated
This code was migrated from the main OASIS API/STAR Metaverse/HoloNET/.NET HDK code found here: https://github.com/NextGenSoftwareUK/Our-World-OASIS-API-HoloNET-HoloUnity-And-.NET-HDK
Background
Original HoloNET code was written back in 2019 and was fully operational with the previous version of Holochain (Redux), but unfortuntley had issues getting it working with RSM (Refactored State Model/latest version)
https://www.ourworldthegame.com/single-post/2019/08/14/world-exclusive-holochain-talking-to-unity
The previous version also came bundled with the holochain conductor so it could auto-start/shutdown the conductor and be fully integrated with any .NET or Unity application. This code/fuctionaility is still in there and will now work again that we have a Windows binary again (NixOS broke this feature previously).
It was featured on Dev Pulse 44 here:
https://medium.com/holochain/updated-quick-start-guide-the-gift-of-holonet-and-conversations-that-matter-on-the-holochain-8e08efde1f58
https://www.ourworldthegame.com/single-post/2019/09/10/holonet-was-featured-in-the-latest-holochain-dev-pulse
Initial RSM Version
We are pleased that after nearly 2 years we have now finally got this upgraded to work with RSM thanks to Connors help, who we are eternally grateful to! 😃
https://www.ourworldthegame.com/single-post/holonet-rsm-breakthrough-at-long-last
Please check out the above link, there you will find more details on what has changed from the previous Redux HoloNET version as well as some documentation on how to use it... 😃
We will also add it here soon...
Donations Welcome! Thank you!

How To Use HoloNET
NOTE: This documentation is best viewed on our github repo (https://github.com/holochain-open-dev/holochain-client-csharp) rather than on NuGet because NuGet has trouble displaying markdown correctly. 😃
The HoloNET Stack
The HoloNET Stack can be found below:
<img src="https://github.com/holochain-open-dev/holochain-client-csharp/blob/main/HoloNET%20Stack.svg"/>
3 Ways To Use HoloNET
As the diagram above shows, there are 3 ways you can use HoloNET:
Can make calls directly to the Holochain Conductor via the HoloNETClient class.
Can extend the HoloNETEntryBaseClass to wrap around the
HoloNETClient
making it quicker and easier to build your app. TheHoloNETEntryBaseClass represents a Holochain Entry within your hApp. This automatically handles mapping the data returned from the Holochain Conductor onto your custom data object properties(Holochain Entry Class) and provides very simple to use Load, Save and Delete methods.Can extend the HoloNETAuditEntryBaseClass, which in itself extends the HoloNETEntryBaseClass providing additional auditing and version control capabilities.
NOTE: The HoloNETClient also provides automatic mapping via some of the CallZomeFunction overloads.
Quick Start
You start by instantiating a new HoloNETClient class passing in the holochain websocket URI to the constructor as seen below:
HoloNETClient holoNETClient = new HoloNETClient("ws://localhost:8888");
Next, you can subscribe to a number of different events:
holoNETClient.OnConnected += HoloNETClient_OnConnected;
holoNETClient.OnAppInfoCallBack += HoloNETClient_OnAppInfoCallBack;
holoNETClient.OnReadyForZomeCalls += HoloNETClient_OnReadyForZomeCalls;
holoNETClient.OnDataReceived += HoloNETClient_OnDataReceived;
holoNETClient.OnZomeFunctionCallBack += HoloNETClient_OnZomeFunctionCallBack;
holoNETClient.OnSignalCallBack += HoloNETClient_OnSignalsCallBack;
holoNETClient.OnDisconnected += HoloNETClient_OnDisconnected;
holoNETClient.OnError += HoloNETClient_OnError;
holoNETClient.OnConductorDebugCallBack += HoloNETClient_OnConductorDebugCallBack;
holoNETClient.OnHolochainConductorsShutdownComplete += _holoNETClient_OnHolochainConductorsShutdownComplete;
holoNETClient.OnHoloNETShutdownComplete += _holoNETClient_OnHoloNETShutdownComplete;
Now you can call the Connect method to connect to Holochain.
await holoNETClient.Connect();
The Connection method has two optional parameters, the first is retrieveAgentPubKeyAndDnaHashFromConductor and the second is retrieveAgentPubKeyAndDnaHashFromSandbox, both default to true.
By default HoloNET will automatically query the AgentPubKey & DnaHash from the Conductor, if that fails, it will try from the hc dev sandbox command. If that fails you will need to manually set them.
To manually set the AgentPubKey & DnaHash use the following:
//Use this if you to manually pass in the AgentPubKey &DnaHash(otherwise it will be automatically queried from the conductor or sandbox).
_holoNETClient.Config.AgentPubKey = "YOUR KEY";
_holoNETClient.Config.DnaHash = "YOUR HASH";
await _holoNETClient.Connect(false, false);
Once it connects successfully it will raise the OnConnected event and then start automatically querying the conductor for the cell id's containing the AgentPubKey & DnaHash (unless you changed the default params above to false).
It will then raise the OnReadyForZomeCalls event signalling you can now make zome calls to the conductor.
Now you can call one of the CallZomeFunctionAsync() overloads:
await _holoNETClient.CallZomeFunctionAsync("1", "numbers", "add_ten", ZomeCallback, new { number = 10 });
Please see below for more details on the various overloads available for this call as well as the data you get back from this call and the other methods and events you can use...
It is also worth checking out the new HoloNETEntryBaseClass and HoloNETAuditEntryBaseClass, which wrap around the HoloNET Client making it very easy to map your hApp Holochain Entries to your custom C# data classes. They allow very simple CRUD operations (Load, Save & Delete) to be performed on your custom data object that extends these classes. Your custom data object represents the data (Holochain Entry) returned from a zome call and HoloNET will handle the mapping onto your data object automatically.
The Power of .NET Async Methods
You will notice that the above calls have the await
keyword prefixing them. This is how you call an async
method in C#. All of HoloNET, HoloOASIS & OASIS API methods are async methods. This simply means that they do not block the calling thread so if this is running on a UI thread it will not freeze the UI. Using the await
keyword allows you to call an async
method as if it was a synchronous one. This means it will not call the next line until the async method has returned. The power of this is that you no longer need to use lots of messy callback functions cluttering up your code as has been the pass with non-async programming. The code path is also a lot easier to follow and maintain.
Read more here: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/async/
New Hybrid Async/Event Model
Saying this, there may be scenarios where you need to use the older non async style methods and use callbacks instead so starting from HoloNET 2.0.0, it also provides non async versions of each method. On top of this each method now has optional params where you can choose to ask HoloNET to wait for the Holochain Conductor to return a response or to return to the calling method immediately and use a callback event instead.
HoloNETClient
This is the main HoloNETClient that can be used to make calls directly to the Holochain Conductor. Use this if you need full control over what zome functions you are calling and data being sent and returned. It is recommended you use the HoloNetEntryBaseClass or HoloNetAuditEntryBaseClass since these wrap around the HoloNETClient making it quicker and easier to make calls to your hApp and will automatically handle mapping the data returned from the Holochain Conductor onto your custom data object (Holochain Entry) properties. The HoloNETClient also provides automatic mapping via some of the CallZomeFunction overloads.

Constructors
The HoloNETClient has the following constructors:
public HoloNETClient(string holochainConductorURI = "ws://localhost:8888", bool logToConsole = true, bool logToFile = true, string releativePathToLogFolder = "Logs", string logFileName = "HoloNET.log", bool addAdditionalSpaceAfterEachLogEntry = false, bool showColouredLogs = true, ConsoleColor debugColour = ConsoleColor.White, ConsoleColor infoColour = ConsoleColor.Green, ConsoleColor warningColour = ConsoleColor.Yellow, ConsoleColor errorColour = ConsoleColor.Red)
public HoloNETClient(ILogger logger, bool alsoUseDefaultLogger = false, string holochainConductorURI = "ws://localhost:8888")
public HoloNETClient(ILogger logger, bool alsoUseDefaultLogger = false, string holochainConductorURI = "ws://localhost:8888", bool logToConsole = true, bool logToFile = true, string releativePathToLogFolder = "Logs", string logFileName = "HoloNET.log", bool addAdditionalSpaceAfterEachLogEntry = false, bool showColouredLogs = true, ConsoleColor debugColour = ConsoleColor.White, ConsoleColor infoColour = ConsoleColor.Green, ConsoleColor warningColour = ConsoleColor.Yellow, ConsoleColor errorColour = ConsoleColor.Red)
public HoloNETClient(IEnumerable<ILogger> loggers, bool alsoUseDefaultLogger = false, string holochainConductorURI = "ws://localhost:8888")
public HoloNETClient(IEnumerable<ILogger> loggers, bool alsoUseDefaultLogger = false, string holochainConductorURI = "ws://localhost:8888", bool logToConsole = true, bool logToFile = true, string releativePathToLogFolder = "Logs", string logFileName = "HoloNET.log", bool addAdditionalSpaceAfterEachLogEntry = false, bool showColouredLogs = true, ConsoleColor debugColour = ConsoleColor.White, ConsoleColor infoColour = ConsoleColor.Green, ConsoleColor warningColour = ConsoleColor.Yellow, ConsoleColor errorColour = ConsoleColor.Red)

Parameter | Description | |
---|---|---|
EndPoint | The URI EndPoint of the Holochain conductor. | |
Id | The id that made the request. | |
Zome | The zome that made the request. | |
ZomeFunction | The zome function that made the request. | |
ZomeReturnData | The parsed data that the zome function returned. HoloNET will parse & convert the best it can from the Rust Holochain Conductor format to a C# friendly one such as converting from base64 encoding, etc. | |
RawZomeReturnData | The raw binary data that the zome function returned. | |
ZomeReturnHash | The ActionHash returned from a zome call (if it returned one, is null if not). | |
KeyValuePair | Contains all of the data returned from the zome call in a simple Dictionary keyvalue pair. The conductor for some reason returns a complex nested structure so is difficult and tedious to get to all the data needed or to quickly view all of it at once. | |
KeyValuePairAsString | Contains the same data from KeyValuePair but formatted as a simple string, which can be used for logging, displaying, etc. | |
EntryData | The entry dictionary containing the actual user data (after it has been processed/decoded) retrieved from the zome call. This is the property that will be most valuable to the caller. This also now includes a EntryDataObject property containing a dynamic data object that is mapped to the dictionary using the optional type (or actual data object) passed into the CallZomeFunctionAsync method. This effectively maps the rust data struct properties contained in the hApp to your C# data object/class. It also contains additional metadata returned from the Holochain Conductor. | |
RawBinaryData | The raw binary data returned from the Holochain conductor. | |
RawBinaryDataAsString | The raw binary data returned from the Holochain conductor formatted as a string (useful for debugging/logging etc). | |
RawBinaryDataDecoded | The raw binary data returned from the Holochain conductor decoded into a string using UTF8 encoding. | |
RawBinaryDataAfterMessagePackDecode | The raw binary data after it has been decoded by MessagePack. | |
RawBinaryDataAfterMessagePackDecodeAsString | The raw binary data after it has been decoded by MessagePack formatted as a string (useful for debugging/logging etc). | |
RawBinaryDataAfterMessagePackDecodeDecoded | The raw binary data after it has been decoded by MessagePack decoded into a string using UTF8 encoding. | |
RawJSONData | The raw JSON data returned from the Holochain conductor. | |
WebSocketResult | Contains more detailed technical information of the underlying websocket. This includes the number of bytes received, whether the message was fully received & whether the message is UTF-8 or binary. Please see here for more info. | |
IsError | True if there was an error during the initialization, false if not. | |
Message | If there was an error this will contain the error message, this normally includes a stacktrace to help you track down the cause. If there was no error it can contain any other message such as status etc or will be blank. |
NOTE: The same EntryData property is also used on the HoloNETEntryBaseClass where you can find the full list of paremeters/sub-properties and their corresponding descriptions contained in the EntryData property.
As an example of how to access the entry data and see it mapped to your custom type/object check out the HoloNET Test Harness, especially this function below:
private static void HoloNETClient_OnZomeFunctionCallBack(object sender, ZomeFunctionCallBackEventArgs e)
{
bool disconect = false;
Console.WriteLine(string.Concat("TEST HARNESS: ZOME FUNCTION CALLBACK EVENT HANDLER: ", ProcessZomeFunctionCallBackEventArgs(e)));
Console.WriteLine("");
}
private static string ProcessZomeFunctionCallBackEventArgs(ZomeFunctionCallBackEventArgs args)
{
string result = "";
result = string.Concat("\nEndPoint: ", args.EndPoint, "\nId: ", args.Id, "\nZome: ", args.Zome, "\nZomeFunction: ", args.ZomeFunction, "\n\nZomeReturnData: ", args.ZomeReturnData, "\nZomeReturnHash: ", args.ZomeReturnHash, "\nRaw Zome Return Data: ", args.RawZomeReturnData, "\nRaw Binary Data: ", args.RawBinaryData, "\nRaw Binary Data As String: ", args.RawBinaryDataAsString, "\nRaw Binary Data Decoded: ", args.RawBinaryDataDecoded, "\nRaw Binary Data After MessagePack Decode: ", args.RawBinaryDataAfterMessagePackDecode, "\nRaw Binary Data After MessagePack Decode As String: ", args.RawBinaryDataAfterMessagePackDecodeAsString, "\nRaw Binary Data Decoded After MessagePack Decode: ", args.RawBinaryDataAfterMessagePackDecodeDecoded, "\nRaw JSON Data: ", args.RawJSONData, "\nIsCallSuccessful: ", args.IsCallSuccessful ? "true" : "false", "\nIsError: ", args.IsError ? "true" : "false", "\nMessage: ", args.Message);
if (!string.IsNullOrEmpty(args.KeyValuePairAsString))
result = string.Concat(result, "\n\nProcessed Zome Return Data:\n", args.KeyValuePairAsString);
if (args.Entry != null && args.Entry.EntryDataObject != null)
{
AvatarEntryDataObject avatar = args.Entry.EntryDataObject as AvatarEntryDataObject;
if (avatar != null)
result = BuildEntryDataObjectMessage(avatar, "Entry.EntryDataObject", result);
}
if (_avatarEntryDataObject != null)
result = BuildEntryDataObjectMessage(_avatarEntryDataObject, "Global.EntryDataObject", result);
return result;
}
private static string BuildEntryDataObjectMessage(AvatarEntryDataObject avatar, string header, string message)
{
message = string.Concat(message, "\n\n", header, ".FirstName: ", avatar.FirstName);
message = string.Concat(message, "\n", header, ".LastName: ", avatar.LastName);
message = string.Concat(message, "\n", header, ".Email: ", avatar.Email);
message = string.Concat(message, "\n", header, ".DOB: ", avatar.DOB);
return message;
}
This is how you can map your rust data to a C# object, the call to the Holochain Conductor is in another earlier place in the Test Harness:
_holoNETClient.CallZomeFunctionAsync("oasis", "get_entry_avatar", ZomeCallback, e.ZomeReturnHash, typeof(AvatarEntryDataObject));
And the AvatarEntryDataObject class/type looks like this:
/// <summary>
/// This example is to be used with the CallZomeFunction overloads on HoloNETClient that take either a type of the EntryDataObject (Type entryDataObjectTypeReturnedFromZome) to map the zome function returned data onto or the actual instance of a dynamic object (dynamic entryDataObjectReturnedFromZome) to map onto.
/// </summary>

Methods
HoloNETClient contains the following methods:
Method | Description | |
---|---|---|
Connect | This method simply connects to the Holochain conductor. It raises the OnConnected event once it is has successfully established a connection. It then calls the RetrieveAgentPubKeyAndDnaHash method to retrieve the AgentPubKey & DnaHash. If the connectedCallBackMode flag is set to WaitForHolochainConductorToConnect (default) it will await until it is connected before returning, otherwise it will return immediately and then call the OnConnected event once it has finished connecting. |
|
StartConductor | This method will start the Holochain Conducutor using the appropriate settings defined in the HoloNETConfig. | |
RetrieveAgentPubKeyAndDnaHash | This method will retrieve the AgentPubKey & DnaHash from either the Holochain Conductor or HC Sandbox depending on what params are passed in. It will default to retrieving from the Conductor first. It will call RetrieveAgentPubKeyAndDnaHashFromConductor and RetrieveAgentPubKeyAndDnaHashFromSandboxAsync internally. | |
RetrieveAgentPubKeyAndDnaHashFromSandbox | This method gets the AgentPubKey & DnaHash from the HC Sandbox command. It will raise the OnReadyForZomeCalls event once it successfully retrieves them and the WebSocket has connected to the Holochain Conductor. If it fails to retrieve the AgentPubKey and DnaHash from the HC Sandbox and the optional automaticallyAttemptToRetrieveFromConductorIfSandBoxFails flag is true (defaults to true), it will call the |
retrieveAgentPubKeyAndDnaHashFromConductor method to attempt to retrieve them directly from the conductor (default). |
RetrieveAgentPubKeyAndDnaHashFromConductor | This method gets the AgentPubKey & DnaHash from the Holochain Conductor (the Connect method will automatically call this by default). Once it has retrieved them and the WebSocket has connceted to the Holochain Conductor it will raise the OnReadyForZomeCalls event. If it fails to retrieve the AgentPubKey and DnaHash from the Conductor and the optional automaticallyAttemptToRetrieveFromSandBoxIfConductorFails flag is true (defaults to true), it will call the |
retrieveAgentPubKeyAndDnaHashFromSandbox method. |
SendHoloNETRequest | This method allows you to send your own raw request to holochain. This method raises the OnDataReceived event once it has received a response from the Holochain conductor. Please see the Events section above for more info on how to use this event. You would rarely need to use this and we highly recommend you use the CallZomeFunctionAsync method instead. You can specify if HoloNET should wait until it has finished disconnecting and shutting down the conductors before returning to the caller or whether it should return immediately and then use the OnDisconnected, OnHolochainConductorsShutdownComplete & OnHoloNETShutdownComplete events to notify the caller. | |
CallZomeFunction | This is the main method you will be using to invoke zome functions on your given zome. It has a number of handy overloads making it easier and more powerful to call your zome functions and manage the returned data. This method raises the OnZomeFunctionCallBack event once it has received a response from the Holochain conductor. | |
Disconnect | This method disconnects the client from the Holochain conductor. It raises the OnDisconnected event once it is has successfully disconnected. It will then automatically call the ShutDownHolochainConductors method (if the shutdownHolochainConductorsMode flag (defaults to UseConfigSettings ) is not set to DoNotShutdownAnyConductors ). If the disconnectedCallBackMode flag is set to WaitForHolochainConductorToDisconnect (default) then it will await until it has disconnected before returning to the caller, otherwise it will return immediately and then raise the OnDisconnected once it is disconnected. |
|
ShutDownHolochainConductors | Will automatically shutdown the current Holochain Conductor (if the shutdownHolochainConductorsMode param is set to ShutdownCurrentConductorOnly ) or all Holochain Conductors (if the shutdownHolochainConductorsMode param is set to ShutdownAllConductors ). If the shutdownHolochainConductorsMode param is set to UseConfigSettings then it will use the HoloNETClient.Config.AutoShutdownHolochainConductor and HoloNETClient.Config.ShutDownALLHolochainConductors flags to determine which mode to use. The Disconnect method will automatically call this once it has finished disconnecting from the Holochain Conductor. The ShutdownHoloNET will also call this method. |
|
ShutdownHoloNET | This method will shutdown HoloNET by first calling the Disconnect method to disconnect from the Holochain Conductor and then calling the ShutDownHolochainConductors method to shutdown any running Holochain Conductors. This method will then raise the OnHoloNETShutdown event. | |
ClearCache | Call this method to clear all of HoloNETClient's internal cache. This includes the responses that have been cached using the CallZomeFunction methods if the cacheData param was set to true for any of the calls. |
|
ConvertHoloHashToBytes | Utility method to convert a string to base64 encoded bytes (Holochain Conductor format). This is used to convert the AgentPubKey & DnaHash when making a zome call. | |
ConvertHoloHashToString | Utility method to convert from base64 bytes (Holochain Conductor format) to a friendly C# format. This is used to convert the AgentPubKey & DnaHash retrieved from the Conductor. | |
WaitTillReadyForZomeCallsAsync | This method will wait (non blocking) until HoloNET is ready to make zome calls after it has connected to the Holochain Conductor and retrived the AgentPubKey & DnaHash. It will then return to the caller with the AgentPubKey & DnaHash. This method will return the same time the OnReadyForZomeCalls event is raised. Unlike all the other methods, this one only contains an async version because the non async version would block all other threads including any UI ones etc. | |
MapEntryDataObject | This method maps the data returned from the Conductor zome call onto a dynamic data object passed into the CallZomeFunction method. Alternatively the type of the data object can be passed in, for which an instance of it will be created. Either way the now mapped and populated data object is then returned in the ZomeFunctionCallBackEventArgs.EntryData.EntryDataObject property during the OnZomeFunctionCallBack event. Please see OnZomeFunctionCallBack for more info. This method is called internally but can also be called manually and is used by the HoloNETEntryBaseClass and HoloNETAuditEntryBaseClass. |
NOTE: All methods contain both a non async version and async version to cater for all use case scenarios.
Connect
This method simply connects to the Holochain conductor. It raises the OnConnected event once it is has successfully established a connection. It then calls the RetrieveAgentPubKeyAndDnaHash method to retrieve the AgentPubKey & DnaHash. If the connectedCallBackMode
flag is set to WaitForHolochainConductorToConnect
(default) it will await until it is connected before returning, otherwise it will return immediately and then call the OnConnected event once it has finished connecting. Please see the Events section above for more info on how to use this event.

If it fails to retrieve the AgentPubKey and DnaHash from the Conductor and the optional automaticallyAttemptToRetrieveFromSandBoxIfConductorFails
flag is true (defaults to true), it will call the RetrieveAgentPubKeyAndDnaHashFromSandbox method.
public async Task<AgentPubKeyDnaHash> RetrieveAgentPubKeyAndDnaHashFromConductorAsync(RetrieveAgentPubKeyAndDnaHashMode retrieveAgentPubKeyAndDnaHashMode = RetrieveAgentPubKeyAndDnaHashMode.Wait, bool updateConfigWithAgentPubKeyAndDnaHashOnceRetrieved = true, bool automaticallyAttemptToRetrieveFromSandBoxIfConductorFails = true)
public AgentPubKeyDnaHash RetrieveAgentPubKeyAndDnaHashFromConductor(bool updateConfigWithAgentPubKeyAndDnaHashOnceRetrieved = true, bool automaticallyAttemptToRetrieveFromSandBoxIfConductorFails = true)
Parameter | Description |
---|---|
retrieveAgentPubKeyAndDnaHashMode | If set to Wait (default) it will await until it has finished retrieving the AgentPubKey & DnaHash before returning, otherwise it will return immediately and then raise the OnReadyForZomeCalls event once it has finished retrieving the DnaHash & AgentPubKey. |
automaticallyAttemptToRetrieveFromSandBoxIfConductorFails | If this is set to true it will automatically attempt to get the AgentPubKey & DnaHash from the HC Sandbox command if it fails to get them from the Holochain Conductor. This defaults to true. |
updateConfigWithAgentPubKeyAndDnaHashOnceRetrieved | Set this to true (default) to automatically update the HoloNETConfig once it has retrieved the DnaHash & AgentPubKey. |
SendHoloNETRequest
This method allows you to send your own raw request to holochain. This method raises the OnDataRecived event once it has received a response from the Holochain conductor. Please see the Events section above for more info on how to use this event.
You would rarely need to use this and we highly recommend you use the CallZomeFunctionAsync method instead.
public async Task SendHoloNETRequestAsync(string id, HoloNETData holoNETData)
public async Task SendHoloNETRequest(string id, HoloNETData holoNETData)
Parameter | Description |
---|---|
id | The id of the request to send to the Holochain Conductor. This will be matched to the id in the response received from the Holochain Conductor. |
holoNETData | The raw data packet you wish to send to the Holochain conductor. |
CallZomeFunction
This is the main method you will be using to invoke zome functions on your given zome. It has a number of handy overloads making it easier and more powerful to call your zome functions and manage the returned data.
This method raises the OnDataReceived event and then either the OnZomeFunctionCallBack or OnSignalCallBack event once it has received a response from the Holochain conductor. Please see the Events section above for more info on how to use this event.
Parameter | Description |
---|---|
id | The unique id you wish to assign for this call. This id is then returned in OnDataReceived, OnZomeFunctionCallBack and OnSignalCallBack events. There are overloads that omit this param, use these overloads if you wish HoloNET to auto-generate and manage the id's for you. |
zome | The name of the zome you wish to target. |
function | The name of the zome function you wish to call. |
callback | A delegate to call once the zome function returns. This delegate contains the same signature as the one used for the OnZomeFunctionCallBack event. (optional param). |
paramsObject | A basic CLR object containing the params the zome function is expecting (optional param). |
matchIdToInstanceZomeFuncInCallback | This is an optional param, which defaults to true. Set this to true if you wish HoloNET to give the instance, zome zome function that made the call in the callback/event. If this is false then only the id will be given in the callback. This uses a small internal cache to match up the id to the given zome/function. Set this to false if you wish to save a tiny amount of memory by not utilizing this cache. If it is false then the Zome and ZomeFunction params will be missing in the ZomeCallBack, you will need to manually match the id to the call yourself. |
cachReturnData | This is an optional param, which defaults to false. Set this to true if you wish HoloNET to cache the response retrieved from holochain. Subsequent calls will return this cached data rather than calling the Holochain conductor again. Use this for static data that is not going to change for performance gains. |
entryDataObjectTypeReturnedFromZome | This is an optional param, where the caller can pass in the type of the dynamic data object they wish the entry data returned to be mapped to. This newly created data object will then be returned in the ZomeFunctionCallBackEventArgs.Entry.EntryDataObject property. |
entryDataObjectReturnedFromZome | This is an optional param, where the caller can pass in an instance of the dynamic data object they wish the entry data returned to be mapped to. This data object will then be returned in the ZomeFunctionCallBackEventArgs.Entry.EntryDataObject property. |
zomeResultCallBackMode | This is an optional param, where the caller can choose whether to wait for the Holochain Conductor response before returning to the caller or to return immediately once the request has been sent to the Holochain Conductor and then raise the OnDataReceived and then the OnZomeFunctionCallBack or OnSignalCallBack events depending on the type of request sent to the Holochain Conductor. |
NOTE - If you pass in the entryDataObjectTypeReturnedFromZome type then you need to make sure on that type definition (class) you specify the Holochain Property Names defined in the hApp rust code as shown in the following example:
NOTE - You can alternatively use other overloads below that take a optional param of entryDataObjectReturnedFromZome instead of entryDataObjectTypeReturnedFromZome. You then pass in an instance of the object you wish to have the properties mapped to the data returned from the zome call.
public class Avatar
{
[HolochainFieldName("first_name")]
public string FirstName { get; set; }
[HolochainFieldName("last_name")]
public string LastName { get; set; }
[HolochainFieldName("email")]
public string Email { get; set; }
[HolochainFieldName("dob")]
public DateTime DOB { get; set; }
}
This would then be used like this:
_holoNETClient.CallZomeFunctionAsync("oasis", "get_entry_avatar", ZomeCallback, e.ZomeReturnHash, true, false, typeof(Avatar));
Where e.ZomeReturnHash is the hash of the entry to load. This is part of the example used in the HoloNET Test Harness, and the e.ZomeReturnHash is the hash returned from the previous call to CallZomeFunctionAsync where the zome function "create_oasis_entry" was called.
Please see the OnZomeFunctionCallBack event for more info on how to then map the data returned to your custom class.

This overload is similar to the one above except you pass in the actual dynamic data object that will be populated/updated with the results from the zome function response using the entryDataObjectReturnedFromZome paramerter.
Overload 3
public async Task<ZomeFunctionCallBackEventArgs> CallZomeFunctionAsync(string zome, string function, ZomeFunctionCallBack callback, object paramsObject, bool cachReturnData = false, Type entryDataObjectTypeReturnedFromZome = null, ZomeResultCallBackMode zomeResultCallBackMode = ZomeResultCallBackMode.WaitForHolochainConductorResponse)

This overload is similar to the first one, except it is missing the callback
param. For this overload you would subscribe to the OnZomeFunctionCallBack
event. You can of course subscribe to this event for the other overloads too, it just means you will then get two callbacks, one for the event handler for OnZomeFunctionalCallBack
and one for the callback delegate you pass in as a param to this method. The choice is yours on how you wish to use this method...

Disconnect
This method disconnects the client from the Holochain conductor. It raises the OnDisconnected event once it is has successfully disconnected. It will then automatically call the ShutDownAllHolochainConductors method (if the shutdownHolochainConductorsMode
flag (defaults to UseConfigSettings
) is not set to DoNotShutdownAnyConductors
). If the disconnectedCallBackMode
flag is set to WaitForHolochainConductorToDisconnect
(default) then it will await until it has disconnected before returning to the caller, otherwise it will return immediately and then raise the OnDisconnected once it is disconnected. Please see the Events section above for more info on how to use this event.
public async Task DisconnectAsync(DisconnectedCallBackMode disconnectedCallBackMode = DisconnectedCallBackMode.WaitForHolochainConductorToDisconnect, ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
public void Disconnect(DisconnectedCallBackMode disconnectedCallBackMode = DisconnectedCallBackMode.WaitForHolochainConductorToDisconnect, ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
Parameter | Description |
---|---|
disconnectedCallBackMode | If this is set to WaitForHolochainConductorToDisconnect (default) then it will await until it has disconnected before returning to the caller, otherwise (it is set to UseCallBackEvents ) it will return immediately and then raise the OnDisconnected event once it is disconnected. |
shutdownHolochainConductorsMode | Once it has successfully disconnected it will automatically call the ShutDownAllHolochainConductors method if the shutdownHolochainConductorsMode flag (defaults to UseConfigSettings ) is not set to DoNotShutdownAnyConductors . Other values it can be are 'ShutdownCurrentConductorOnly' or 'ShutdownAllConductors'. Please see the ShutDownConductors method below for more detail. |
ShutDownHolochainConductors
Will automatically shutdown the current Holochain Conductor (if the shutdownHolochainConductorsMode
param is set to ShutdownCurrentConductorOnly
) or all Holochain Conductors (if the shutdownHolochainConductorsMode
param is set to ShutdownAllConductors
). If the shutdownHolochainConductorsMode
param is set to UseConfigSettings
then it will use the HoloNETClient.Config.AutoShutdownHolochainConductor
and HoloNETClient.Config.ShutDownALLHolochainConductors
flags to determine which mode to use. The Disconnect method will automatically call this once it has finished disconnecting from the Holochain Conductor. The ShutdownHoloNET will also call this method.
public async Task<HolochainConductorsShutdownEventArgs> ShutDownHolochainConductorsAsync(ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
public HolochainConductorsShutdownEventArgs ShutDownHolochainConductors(ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
Parameter | Description |
---|---|
shutdownHolochainConductorsMode | If this flag is set to ShutdownCurrentConductorOnly it will shutdown the currently running Holochain Conductor only. If it is set to ShutdownAllConductors it will shutdown all running Holochain Conductors. If it is set to UseConfigSettings (default) then it will use the HoloNETClient.Config.AutoShutdownHolochainConductor and HoloNETClient.Config.ShutDownALLHolochainConductors flags to determine which mode to use. |
ShutdownHoloNET
This method will shutdown HoloNET by first calling the Disconnect method to disconnect from the Holochain Conductor and then calling the ShutDownHolochainConductors method to shutdown any running Holochain Conductors. This method will then raise the OnHoloNETShutdown event. This method works very similar to the Disconnect method except it also clears the loggers, does any other shutdown tasks necessary and then returns a HoloNETShutdownEventArgs
object. You can specify if HoloNET should wait until it has finished disconnecting and shutting down the conductors before returning to the caller or whether it should return immediately and then use the OnDisconnected, OnHolochainConductorsShutdownComplete & OnHoloNETShutdownComplete events to notify the caller.
public async Task<HoloNETShutdownEventArgs> ShutdownHoloNETAsync(DisconnectedCallBackMode disconnectedCallBackMode = DisconnectedCallBackMode.WaitForHolochainConductorToDisconnect, ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
public HoloNETShutdownEventArgs ShutdownHoloNET(ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
Parameter | Description |
---|---|
disconnectedCallBackMode | If this is set to WaitForHolochainConductorToDisconnect (default) then it will await until it has disconnected before returning to the caller, otherwise (it is set to UseCallBackEvents ) it will return immediately and then raise the OnDisconnected once it is disconnected. |
shutdownHolochainConductorsMode | Once it has successfully disconnected it will automatically call the ShutDownAllHolochainConductors method if the shutdownHolochainConductorsMode flag (defaults to UseConfigSettings ) is not set to DoNotShutdownAnyConductors . Other values it can be are 'ShutdownCurrentConductorOnly' or 'ShutdownAllConductors'. Please see the ShutDownConductors method below for more detail. |
ClearCache
Call this method to clear all of HoloNETClient's internal cache. This includes the responses that have been cached using the CallZomeFunction methods if the cacheData
param was set to true for any of the calls.
public void ClearCache()
ConvertHoloHashToBytes
Utility method to convert a string to base64 encoded bytes (Holochain Conductor format). This is used to convert the AgentPubKey & DnaHash when making a zome call.|
public byte[] ConvertHoloHashToBytes(string hash)
ConvertHoloHashToString
Utility method to convert from base64 bytes (Holochain Conductor format) to a friendly C# format. This is used to convert the AgentPubKey & DnaHash retrieved from the Conductor.|
public string ConvertHoloHashToString(byte[] bytes)
WaitTillReadyForZomeCallsAsync
This method will wait (non blocking) until HoloNET is ready to make zome calls after it has connected to the Holochain Conductor and retrived the AgentPubKey & DnaHash. It will then return to the caller with the AgentPubKey & DnaHash. This method will return the same time the OnReadyForZomeCalls event is raised. Unlike all the other methods, this one only contains an async version because the non async version would block all other threads including any UI ones etc.
public async Task<ReadyForZomeCallsEventArgs> WaitTillReadyForZomeCallsAsync()
MapEntryDataObject
This method maps the data returned from the Conductor zome call onto a dynamic data object passed into the CallZomeFunction method. Alternatively the type of the data object can be passed in, for which an instance of it will be created. Either way the now mapped and populated data object is then returned in the ZomeFunctionCallBackEventArgs.EntryData.EntryDataObject
property during the OnZomeFunctionCallBack event. Please see OnZomeFunctionCallBack for more info. This method is called internally but can also be called manually and is used by the HoloNETEntryBaseClass and HoloNETAuditEntryBaseClass.
public async Task<dynamic> MapEntryDataObjectAsync(Type entryDataObjectType, Dictionary<string, string> keyValuePairs)
public dynamic MapEntryDataObject(Type entryDataObjectType, Dictionary<string, string> keyValuePairs)
public async Task<dynamic> MapEntryDataObjectAsync(dynamic entryDataObject, Dictionary<string, string> keyValuePairs)
public dynamic MapEntryDataObject(dynamic entryDataObject, Dictionary<string, string> keyValuePairs)
Parameter | Description |
---|---|
entryDataObjectType | The type of the data object to map the KeyValuePairs returned from the Holochain Conductor onto. |
entryDataObject | The dynamic data object to map the KeyValuePairs returned from the Holochain Conductor onto. |
keyValuePairs | The KeyValuePairs returned from the Holochain Conductor (after they have been decoded by an internal function called DecodeRawZomeData ) that will be mapped onto the data object. |
<a name="HoloNETClientProperties"></a>
Properties
HoloNETClient contains the following properties:
Property | Description |
---|---|
Config | This property contains a struct called HoloNETConfig containing the sub-properties: AgentPubKey, DnaHash, FullPathToRootHappFolder, FullPathToCompiledHappFolder, HolochainConductorMode, FullPathToExternalHolochainConductorBinary, FullPathToExternalHCToolBinary, SecondsToWaitForHolochainConductorToStart, AutoStartHolochainConductor, ShowHolochainConductorWindow, AutoShutdownHolochainConductor, ShutDownALLHolochainConductors, HolochainConductorToUse, OnlyAllowOneHolochainConductorToRunAtATime, LoggingMode & ErrorHandlingBehaviour. |
WebSocket | This property contains the internal NextGenSoftware WebSocket that HoloNET uses. You can use this property to access the current state of the WebSocket as well as configure more options. |
State | This property is a shortcut to the State property on the WebSocket property above. |
EndPoint | This property is a shortcut to the EndPoint property on the WebSocket property above. |
IsReadyForZomesCalls | This property is a boolean and will return true when HoloNET is ready for zome calls after the OnReadyForZomeCalls event is raised. |
RetrievingAgentPubKeyAndDnaHash | This property is a boolean and will return true when HoloNET is retrieving the AgentPubKey & DnaHash using one of the RetrieveAgentPubKeyAndDnaHash, RetrieveAgentPubKeyAndDnaHashFromSandbox or RetrieveAgentPubKeyAndDnaHashFromConductor methods (by default this will occur automatically after it has connected to the Holochain Conductor). |
Config
<a name="HoloNETConfig"/>
This property contains a struct called HoloNETConfig
containing the following sub-properties:
Property | Description |
---|---|
AgentPubKey | The AgentPubKey to use for Zome calls. If this is not set then HoloNET will automatically retrieve this along with the DnaHash after it connects (if the Connect method defaults are not overriden). |
DnaHash | The DnaHash to use for Zome calls. If this is not set then HoloNET will automatically retrieve this along with the AgentPubKey after it connects (if the Connect method defaults are not overriden). |
FullPathToRootHappFolder | The full path to the root of the hApp that HoloNET will start the Holochain Conductor (currenty uses hc.exe) with and then make zome calls to. |
FullPathToCompiledHappFolder | The full path to the compiled hApp that HoloNET will start the Holochain Conductor (currenty uses hc.exe) with and then make zome calls to. |
HolochainConductorMode | Tells HoloNET how to auto-start the Holochain Conductor. It can be one of the following values: UseExternal - Will use the hc.exe specified in the FullPathToExternalHCToolBinary property if HolochainConductorToUse property is set to Hc . It will use the holochain.exe specified in the FullPathToExternalHolochainConductorBinary property if HolochainConductorToUse property is set to Holochain . If HolochainConductorMode is set to UseEmbedded then it will use the embdedded/integrated hc.exe/holochain.exe if the app is using the NextGenSoftware.Holochain.HoloNET.Client.Embedded package, otherwise it will throw an exception. Finally, if HolochainConductorMode is set to UseSystemGlobal (default), then it will automatically use the installed version of hc.exe & holochain.exe on the target machine. |
HolochainConductorToUse | This is the Holochain Conductor to use for the auto-start Holochain Conductor feature. It can be either Holochain or Hc . |
FullPathToExternalHolochainConductorBinary | The full path to the Holochain Conductor exe (holochain.exe) that HoloNET will auto-start if HolochainConductorToUse is set to Holochain . |
FullPathToExternalHCToolBinary | The full path to the Holochain Conductor exe (hc.exe) that HoloNET will auto-start if HolochainConductorToUse is set to Hc . |
SecondsToWaitForHolochainConductorToStart | The seconds to wait for the Holochain Conductor to start before attempting to connect to it. |
AutoStartHolochainConductor | Set this to true if you with HoloNET to auto-start the Holochain Conductor defined in the FullPathToExternalHolochainConductorBinary parameter if HolochainConductorToUseis Holochain, otherwise if it s Hc then it will use FullPathToExternalHCToolBinary . Default is true. |
ShowHolochainConductorWindow | Set this to true if you wish HoloNET to show the Holochain Conductor window whilst it is starting it (will be left open until the conductor is automatically shutdown again when HoloNET disconects if AutoShutdownHolochainConductor is true.) |
AutoShutdownHolochainConductor | Set this to true if you wish HoloNET to auto-shutdown the Holochain Conductor after it disconnects. Default is true. |
ShutDownALLHolochainConductors | Set this to true if you wish HoloNET to auto-shutdown ALL Holochain Conductors after it disconnects. Default is false. Set this to true if you wish to make sure there are none left running to prevent memory leaks. You can also of course manually call the ShutDownAllConductors if you wish. |
OnlyAllowOneHolochainConductorToRunAtATime | Set this to true if you wish HoloNET to allow only ONE Holochain Conductor to run at a time. The default is false. |
LoggingMode | This passes through to the static LogConfig.LoggingMode property in NextGenSoftware.Logging package. It can be either WarningsErrorsInfoAndDebug , WarningsErrorsAndInfo , WarningsAndErrors or ErrorsOnly . |
ErrorHandlingBehaviour | An enum that specifies what to do when anm error occurs. The options are: AlwaysThrowExceptionOnError , OnlyThrowExceptionIfNoErrorHandlerSubscribedToOnErrorEvent & NeverThrowExceptions ). The default is OnlyThrowExceptionIfNoErrorHandlerSubscribedToOnErrorEvent meaning it will only throw an error if the OnError event has not been subscribed to. This delegates error handling to the caller. If no event has been subscribed then HoloNETClient will throw an error. AlwaysThrowExceptionOnError will always throw an error even if the OnError event has been subscribed to. The NeverThrowException enum option will never throw an error even if the OnError event has not been subscribed to. Regardless of what enum is selected, the error will always be logged using whatever ILogger`s have been injected into the constructor or set on the static Logging.Loggers property. |
WebSocket
This property contains a refrence to the internal NextGenSoftware WebSocket that HoloNET uses. You can use this property to access the current state of the WebSocket as well as configure more options.
WebSocket.Config
It has a sub-property called Config that contains the following options:
Property | Description |
---|---|
TimeOutSeconds | The time in seconds before the connection times out when calling either method SendHoloNETRequest or CalLZomeFunction . This defaults to 30 seconds. |
NeverTimeOut | Set this to true if you wish the connection to never time out when making a call from methods SendHoloNETRequest and CallZomeFunction . This defaults to false. |
KeepAliveSeconds | This is the time to keep the connection alive in seconds. This defaults to 30 seconds. |
ReconnectionAttempts | The number of times HoloNETClient will attempt to re-connect if the connection is dropped. The default is 5. |
ReconnectionIntervalSeconds | The time to wait between each re-connection attempt. The default is 5 seconds. |
SendChunkSize | The size of the buffer to use when sending data to the Holochain Conductor. The default is 1024 bytes. |
ReceiveChunkSizeDefault | The size of the buffer to use when receiving data from the Holochain Conductor. The default is 1024 bytes. |
ErrorHandlingBehaviour | An enum that specifies what to do when anm error occurs. The options are: AlwaysThrowExceptionOnError , OnlyThrowExceptionIfNoErrorHandlerSubscribedToOnErrorEvent & NeverThrowExceptions ). The default is OnlyThrowExceptionIfNoErrorHandlerSubscribedToOnErrorEvent meaning it will only throw an error if the OnError event has not been subscribed to. This delegates error handling to the caller. If no event has been subscribed then HoloNETClient will throw an error. AlwaysThrowExceptionOnError will always throw an error even if the OnError event has been subscribed to. The NeverThrowException enum option will never throw an error even if the OnError event has not been subscribed to. Regardless of what enum is selected, the error will always be logged using whatever ILogger s have been injected into the constructor or set on the static Logging.Loggers property. |
WebSocket.State
Contains an enumeration that can be one of the following values:
None, Connecting, Open, CloseSent, CloseReceived, Closed, Aborted
State
Is a shortcut to the WebSocket.State enumeration above.
EndPoint
Is the endpoint URI that HoloNET is running on.
Logging
Both HoloNET & the NextGenSoftware.WebSocket package that HoloNET uses allow either a ILogger or collection of ILogger's to be injected in through Constuctor DI (Depenecy Injection).
public HoloNETClient(string holochainConductorURI = "ws://localhost:8888", bool logToConsole = true, bool logToFile = true, string releativePathToLogFolder = "Logs", string logFileName = "HoloNET.log", bool addAdditionalSpaceAfterEachLogEntry = false, bool showColouredLogs = true, ConsoleColor debugColour = ConsoleColor.White, ConsoleColor infoColour = ConsoleColor.Green, ConsoleColor warningColour = ConsoleColor.Yellow, ConsoleColor errorColour = ConsoleColor.Red)
{
Logging.Logging.Loggers.Add(new DefaultLogger(logToConsole, logToFile, releativePathToLogFolder, logFileName, addAdditionalSpaceAfterEachLogEntry, showColouredLogs, debugColour, infoColour, warningColour, errorColour));
Init(holochainConductorURI);
}
public HoloNETClient(ILogger logger, string holochainConductorURI = "ws://localhost:8888")
{
Logging.Logging.Loggers.Add(logger);
Init(holochainConductorURI);
}
public HoloNETClient(IEnumerable<ILogger> loggers, string holochainConductorURI = "ws://localhost:8888")
{
Logging.Logging.Loggers = new List<ILogger>(loggers);
Init(holochainConductorURI);
}
public WebSocket(string endPointURI, bool logToConsole = true, bool logToFile = true, string releativePathToLogFolder = "Logs", string logFileName = "NextGenSoftwareWebSocket.log", bool addAdditionalSpaceAfterEachLogEntry = false, bool showColouredLogs = true, ConsoleColor debugColour = ConsoleColor.White, ConsoleColor infoColour = ConsoleColor.Green, ConsoleColor warningColour = ConsoleColor.Yellow, ConsoleColor errorColour = ConsoleColor.Red)
{
EndPoint = endPointURI;
Logging.Logging.Loggers.Add(new DefaultLogger(logToConsole, logToFile, releativePathToLogFolder, logFileName, addAdditionalSpaceAfterEachLogEntry, showColouredLogs, debugColour, infoColour, warningColour, errorColour));
Init();
}
public WebSocket(string endPointURI, IEnumerable<ILogger> loggers)
{
EndPoint = endPointURI;
Logging.Logging.Loggers = new List<ILogger>(loggers);
Init();
}
public WebSocket(string endPointURI, ILogger logger)
{
Logging.Logging.Loggers.Add(logger);
EndPoint = endPointURI;
Init();
}
DefaultLogger
All NextGen Software libraries such as HoloNET, WebSocket etc use NextGenSoftware.Logging. By default if no ILogger is injected in then they will automatically use the built in DefaultLogger
, which comes with both File & Animated Coloured Console logging out of the box. Under the hood it uses the NextGenSoftware.CLI.Engine package to enable the colour and animation.
The DefaultLogger has the following options that can also be configured:
Property | Description |
---|---|
LogDirectory | The directory where logs will be created. |
LogFileName | The name of the log file to create. |
LogToConsole | Set this to true to log to the console. The default is true. |
LogToFile | Set this to true to log to the file. The default is true. |
AddAdditionalSpaceAfterEachLogEntry | Set this to true to add additional space after each log entry. The default is false. |
ShowColouredLogs | Set this to true to enable coloured logs in the console. This default to true. |
DebugColour | The colour to use for Debug log entries to the console. |
InfoColour | The colour to use for Info log entries to the console. |
WarningColour | The colour to use for Warning log entries to the console. |
ErrorColour | The colour to use for Error log entries to the console. |
You are welcome to create your own loggers to inject in, you simply need to implement the simple ILogger interface:
public interface ILogger
{
void Log(string message, LogType type, bool showWorkingAnimation = false);
void Log(string message, LogType type, ConsoleColor consoleColour, bool showWorkingAnimation = false);
void Shutdown();
}
The Shutdown method is not used by the DefaultLogger
, and so far is only used by the NextGenSoftware.Logging.NLog package.
HoloNETEntryBaseClass
This is a new abstract class introduced in HoloNET 2 that wraps around the HoloNETClient so you do not need to interact with the client directly. Instead it allows very simple CRUD operations (Load, Save & Delete) to be performed on your custom data object that extends this class. Your custom data object represents the data (Holochain Entry) returned from a zome call and HoloNET will handle the mapping onto your data object automatically.
It has two main types of constructors as can be seen below, one that allows you to pass in a HoloNETClient instance (which can be shared with other classes that extend the HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass) or if you do not pass a HoloNETClient instance in using the other constructor it will create its own internal instance to use just for this class.
Here is a simple example of how to use it:
/// <summary>
/// This example creates its own internal instance of the HoloNETClient, you should only use this if you will be extending only one HoloNETAuditEntryBaseClass/HoloNETEntryBaseClass otherwise use the Multiple Class Example.
/// </summary>
public class Avatar : HoloNETEntryBaseClass
{
public Avatar() : base("oasis", "get_entry_avatar", "create_entry_avatar", "update_entry_avatar", "delete_entry_avatar") { }
public Avatar(HoloNETConfig holoNETConfig) : base("oasis", "get_entry_avatar", "create_entry_avatar", "update_entry_avatar", "delete_entry_avatar", holoNETConfig) { }
[HolochainFieldName("first_name")]
public string FirstName { get; set; }
[HolochainFieldName("last_name")]
public string LastName { get; set; }
[HolochainFieldName("email")]
public string Email { get; set; }
[HolochainFieldName("dob")]
public DateTime DOB { get; set; }
}
And here is the rust code in the hApp that this maps onto:
#[hdk_entry_helper]
#[derive(Clone)]
pub struct Avatar {
pub id: String,
pub first_name: String,
pub last_name: String,
pub email: String,
pub dob: String
}
#[derive(Serialize, Deserialize, Debug)]
pub struct UpdateEntryAvatarInput {
original_action_hash: ActionHash,
updated_entry: Avatar
}
#[hdk_entry_defs]
#[unit_enum(UnitEntryTypes)]
pub enum EntryTypes {
#[entry_def()]
Avatar(Avatar),
}
#[hdk_extern]
pub fn create_entry_avatar(avatar: Avatar) -> ExternResult<ActionHash> {
create_entry(&EntryTypes::Avatar(avatar.clone()))
}
#[hdk_extern]
pub fn get_entry_avatar(action_hash: ActionHash) -> ExternResult<Option<Record>> {
get(action_hash, GetOptions::default())
}
#[hdk_extern]
pub fn update_entry_avatar(input: UpdateEntryAvatarInput) -> ExternResult<ActionHash>
{
update_entry(input.original_action_hash, &input.updated_entry)
}
#[hdk_extern]
pub fn delete_entry_avatar(action_hash: ActionHash) -> ExternResult<ActionHash> {
delete_entry(action_hash)
}
NOTE: Each property that you wish to have mapped to a property/field in your rust code needs to have the HolochainFieldName attribute applied to it specifying the name of the field in your rust struct that is to be mapped to this c# property.
NOTE: This is a preview of some of the advanced functionality that will be present in the upcoming .NET HDK Low Code Generator, which generates dynamic rust and c# code from your metadata freeing you to focus on your amazing business idea and creativity rather than worrying about learning Holochain, Rust and then getting it to all work in Windows and with C#. HAppy Days! 😉

Events
The HoloNETEntryBaseClass has the following events you can subscribe to:
Event | Description |
---|---|
OnError | Fired when there is an error either in HoloNETEntryBaseClass or the HoloNET client itself. |
OnInitialized | Fired after the Initialize method has finished initializing the HoloNET client. This will also call the Connect and RetrieveAgentPubKeyAndDnaHash methods on the HoloNET client. This event is then fired when the HoloNET client has successfully connected to the Holochain Conductor, retrieved the AgentPubKey & DnaHash & then fired the OnReadyForZomeCalls event. See also the IsInitializing and the IsInitialized properties. |
OnLoaded | Fired after the Load method has finished loading the Holochain entry from the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeLoadEntryFunction or property ZomeLoadEntryFunction and then maps the data returned from the zome call onto your data object. |
OnSaved | Fired after the Save method has finished saving the Holochain entry to the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeCreateEntryFunction or property ZomeCreateEntryFunction if it is a new entry (empty object) or the zomeUpdateEntryFunction param and ZomeUpdateEntryFunction property if it's an existing entry (previously saved object containing a valid value for the EntryHash property). Once it has saved the entry it will then update the EntryHash property with the entry hash returned from the zome call/conductor. The PreviousVersionEntryHash property is also set to the previous EntryHash (if there is one). |
OnDeleted | Fired after the Delete method has finished deleting the Holochain entry and has received a response from the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeDeleteEntryFunction or property ZomeDeleteEntryFunction . It then updates the HoloNET Entry Data Object with the response received from the Holochain Conductor. |
OnClosed | Fired after the Close method has finished closing the connection to the Holochain Conductor and has shutdown all running Holochain Conductors (if configured to do so). This method calls the ShutdownHoloNET internally. |
OnError
Fired when there is an error either in HoloNETEntryBaseClass or the HoloNET client itself.
holoNETEntryBaseClass.OnError += holoNETEntryBaseClass_OnError;
private static void holoNETEntryBaseClass_OnError(object sender, HoloNETErrorEventArgs e)

}
Parameter | Description |
---|---|
EndPoint | The URI EndPoint of the Holochain conductor. |
Reason | The reason for the error. |
OnInitialized
Fired after the Initialize method has finished initializing the HoloNET client. This will also call the Connect and RetrieveAgentPubKeyAndDnaHash methods on the HoloNET client. This event is then fired when the HoloNET client has successfully connected to the Holochain Conductor, retrieved the AgentPubKey & DnaHash & then fired the OnReadyForZomeCalls event. See also the IsInitializing and the IsInitialized properties.
holoNETEntryBaseClass.OnInitialized += holoNETEntryBaseClass_OnInitialized;

CLIEngine.ShowMessage($"TEST HARNESS: holoNETEntryBaseClass_OnInitialized, EndPoint: {e.EndPoint}, AgentPubKey: {e.AgentPubKey}, DnaHash: {e.DnaHash}, IsError: {e.IsError}, Message: {e.Message}");
}
Parameter | Description |
---|---|
EndPoint | The URI EndPoint of the Holochain conductor. |
AgentPubKey | The Agent Public Key of the hApp that was running in the Holochain Conductor. |
DnaHash | The DNA Hash of the hApp that was running in the Holochain Conductor. |
IsError | True if there was an error during the initialization, false if not. |
Message | If there was an error this will contain the error message, this normally includes a stacktrace to help you track down the cause. If there was no error it can contain any other message such as status etc or will be blank. |
OnLoaded
Fired after the Load method has finished loading the Holochain entry from the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeLoadEntryFunction
or property ZomeLoadEntryFunction
and then maps the data returned from the zome call onto your data object.
holoNETEntryBaseClass.OnLoaded += holoNETEntryBaseClass_OnLoaded;

or property ZomeCreateEntryFunction if it is a new entry (empty object) or the zomeUpdateEntryFunction
param and ZomeUpdateEntryFunction property if it's an existing entry (previously saved object containing a valid value for the EntryHash property). Once it has saved the entry it will then update the EntryHash property with the entry hash returned from the zome call/conductor. The PreviousVersionEntryHash property is also set to the previous EntryHash (if there is one).
holoNETEntryBaseClass.OnSaved += holoNETEntryBaseClass_OnSaved;
private static void holoNETEntryBaseClass_OnSaved(object sender, ZomeFunctionCallBackEventArgs e)

}
NOTE: This uses the same ZomeFunctionCallBackEventArgs
as the OnZomeFunctionCallBack event so please check there for the list of parameters returned by this event.
OnDeleted
Fired after the Delete method has finished deleting the Holochain entry and has received a response from the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeDeleteEntryFunction
or property ZomeDeleteEntryFunction

<a name="HoloNETEntryBaseClassMethods"></a>
Methods
The HoloNETEntryBaseClass has the following methods:
Method | Description |
---|---|
Initialize | This method will Initialize the HoloNETEntryBaseClass along with the internal HoloNET Client and will raise the OnInitialized event once it has finished initializing. This will also call the Connect and RetrieveAgentPubKeyAndDnaHash methods on the HoloNET client. Once the HoloNET client has successfully connected to the Holochain Conductor, retrieved the AgentPubKey & DnaHash & then raised the OnReadyForZomeCalls event it will raise the OnInitialized event. See also the IsInitializing and the IsInitialized properties. |
Load | This method will load the Holochain entry from the Holochain Conductor using either the EntryHash property or entryHash param passed into one of the overloads for this method. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeLoadEntryFunction or property ZomeLoadEntryFunction and then maps the data returned from the zome call onto your data object. It will then raise the OnLoaded event. NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info... |
Save | This method will save the Holochain entry to the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeCreateEntryFunction or property ZomeCreateEntryFunction if it is a new entry (empty object) or the zomeUpdateEntryFunction param and ZomeUpdateEntryFunction property if it's an existing entry (previously saved object containing a valid value for the EntryHash property). Once it has saved the entry it will then update the EntryHash property with the entry hash returned from the zome call/conductor. The PreviousVersionEntryHash property is also set to the previous EntryHash (if there is one). Once it has finished saving and got a response from the Holochain Conductor it will raise the OnSaved event. NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info... NOTE: The parmeterless overload will automatically extrct the properties that need saving (contain the HolochainFieldName attribute). This method uses reflection so has a tiny performance overhead (negligbale), but if you need the extra nanoseconds use the other Save overload passing in your own params object. |
Delete | This method will soft delete the Holochain entry (the previous version can still be retrieved). This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeDeleteEntryFunction or property ZomeDeleteEntryFunction. It then updates the HoloNET Entry Data Object with the response received from the Holochain Conductor and then finally raises the OnDeleted event. NOTE: The parmeterless overload will automatically extrct the properties that need saving (contain the HolochainFieldName attribute). This method uses reflection so has a tiny performance overhead (negligbale), but if you need the extra nanoseconds use the other Save overload passing in your own params object. |
Close | Will close this HoloNET Entry and then shutdown its internal HoloNET instance (if one was not passed in) and its current connetion to the Holochain Conductor and then shutdown all running Holochain Conductors (if configured to do so) as well as any other tasks to shut HoloNET down cleanly. This method calls the ShutdownHoloNET method internally. Once it has finished shutting down HoloNET it will raise the OnClosed event. You can specify if HoloNET should wait until it has finished disconnecting and shutting down the conductors before returning to the caller or whether it should return immediately and then use the OnDisconnected, OnHolochainConductorsShutdownComplete & OnHoloNETShutdownComplete events to notify the caller. |
WaitTillHoloNETInitializedAsync | This mehod will call the WaitTillReadyForZomeCallsAsync method on the HoloNET Client. |
ClearCache | Clears the PropertyInfo cache used during the Save methods that use reflection to dynamically build the params for the zome function (save/update). |
Initialize
This method will Initialize the HoloNETEntryBaseClass along with the internal HoloNET Client and will raise the OnInitialized event once it has finished initializing. This will also call the Connect and RetrieveAgentPubKeyAndDnaHash methods on the HoloNET client. Once the HoloNET client has successfully connected to the Holochain Conductor, retrieved the AgentPubKey & DnaHash & then raised the OnReadyForZomeCalls event it will raise the OnInitialized event. See also the IsInitializing and the IsInitialized properties.
public virtual async Task InitializeAsync(ConnectedCallBackMode connectedCallBackMode = ConnectedCallBackMode.WaitForHolochainConductorToConnect, RetrieveAgentPubKeyAndDnaHashMode retrieveAgentPubKeyAndDnaHashMode = RetrieveAgentPubKeyAndDnaHashMode.Wait, bool retrieveAgentPubKeyAndDnaHashFromConductor = true, bool retrieveAgentPubKeyAndDnaHashFromSandbox = true, bool automaticallyAttemptToRetrieveFromConductorIfSandBoxFails = true, bool automaticallyAttemptToRetrieveFromSandBoxIfConductorFails = true, bool updateConfigWithAgentPubKeyAndDnaHashOnceRetrieved = true)

Parameter | Description |
---|---|
connectedCallBackMode | If set to WaitForHolochainConductorToConnect (default) it will await until it is connected before returning, otherwise it will return immediately and then call the OnConnected event once it has finished connecting. |
retrieveAgentPubKeyAndDnaHashMode | If set to Wait (default) it will await until it has finished retrieving the AgentPubKey & DnaHash before returning, otherwise it will return immediately and then call the OnReadyForZomeCalls event once it has finished retrieving the DnaHash & AgentPubKey. |
retrieveAgentPubKeyAndDnaHashFromConductor | Set this to true for HoloNET to automatically retrieve the AgentPubKey & DnaHash from the Holochain Conductor after it has connected. This defaults to true. |
retrieveAgentPubKeyAndDnaHashFromSandbox | Set this to true if you wish HoloNET to automatically retrieve the AgentPubKey & DnaHash from the hc sandbox after it has connected. This defaults to true. |
automaticallyAttemptToRetrieveFromConductorIfSandBoxFails | If this is set to true it will automatically attempt to get the AgentPubKey & DnaHash from the Holochain Conductor if it fails to get them from the HC Sandbox command. This defaults to true. |
automaticallyAttemptToRetrieveFromSandBoxIfConductorFails | If this is set to true it will automatically attempt to get the AgentPubKey & DnaHash from the HC Sandbox command if it fails to get them from the Holochain Conductor. This defaults to true. |
updateConfigWithAgentPubKeyAndDnaHashOnceRetrieved | Set this to true (default) to automatically update the HoloNETConfig once it has retrieved the DnaHash & AgentPubKey. |
Load
This method will load the Holochain entry from the Holochain Conductor using either the EntryHash property or entryHash
param passed into one of the overloads for this method. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeLoadEntryFunction
or property ZomeLoadEntryFunction
and then maps the data returned from the zome call onto your data object. It will then raise the OnLoaded event.
NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info...
public virtual async Task<ZomeFunctionCallBackEventArgs> LoadAsync(string entryHash, Dictionary<string, string> customDataKeyValuePairs = null, useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
public virtual ZomeFunctionCallBackEventArgs Load(string entryHash, Dictionary<string, string> customDataKeyValuePairs = null, useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)

public virtual ZomeFunctionCallBackEventArgs Load(string customFieldToLoadByValue, string customFieldToLoadByKey = "", Dictionary<string, string> customDataKeyValuePairs = null, bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
Parameter | Description |
---|---|
entryHash | The hash of the Holochain Entry you wish to load. For the overloads that do not take the entryHash as a paramater it will use the EntryHash property. |
customFieldToLoadByValue | The custom field value to load by (if you do not wish to load by the EntryHash). |
customFieldToLoadByKey | The custom field key to load by (if you do not wish to load by the EntryHash). NOTE: This field is only needed if you also pass in a customDataKeyValuePairs dictionary otherwise only the customFieldToLoadByValue is required. If no customDataKeyValuePairs is passed in then this field (customFieldToLoadByKey) will be ignored. |
customDataKeyValuePairs | This is an optional param where a dictionary containing additional params (KeyValue Pairs) can be passed to the zome function. If this is passed in then the entryHash or customFieldToLoadByValue will automatically be added to the new params with key entry_hash (make sure your hApp zome function is expecting this name) or customFieldToLoadByKey. |
useReflectionToMapKeyValuePairResponseOntoEntryDataObject | This is an optional param, set this to true (default) to map the data returned from the Holochain Conductor onto the Entry Data Object that extends this base class (HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass). This will have a very small performance overhead but means you do not need to do the mapping yourself from the ZomeFunctionCallBackEventArgs.KeyValuePair. |
Save
This method will save the Holochain entry to the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeCreateEntryFunction
or property ZomeCreateEntryFunction if it is a new entry (empty object) or the zomeUpdateEntryFunction
param and ZomeUpdateEntryFunction property if it's an existing entry (previously saved object containing a valid value for the EntryHash property). Once it has saved the entry it will then update the EntryHash property with the entry hash returned from the zome call/conductor. The PreviousVersionEntryHash property is also set to the previous EntryHash (if there is one). Once it has finished saving and got a response from the Holochain Conductor it will raise the OnSaved event.
NOTE: The overloads that do not have the paramsObject param will automatically extrct the properties that need saving (contain the HolochainFieldName attribute). This method uses reflection so has a tiny performance overhead (negligbale), but if you need the extra nanoseconds use the other Save overload passing in your own params object.
NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info...
public virtual async Task<ZomeFunctionCallBackEventArgs> SaveAsync(Dictionary<string, string> customDataKeyValuePairs = null, Dictionary<string, bool> holochainFieldsIsEnabledKeyValuePairs = null, bool cachePropertyInfos = true, bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
public virtual ZomeFunctionCallBackEventArgs Save(Dictionary<string, string> customDataKeyValuePairs = null, Dictionary<string, bool> holochainFieldsIsEnabledKeyValuePairs = null, bool cachePropertyInfos = true, bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
public virtual async Task<ZomeFunctionCallBackEventArgs> SaveAsync(dynamic paramsObject, bool autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams = true, string updatedEntryRustParamName = "updated_entry", string originalEntryHashRustParamName = "original_action_hash", bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
public virtual ZomeFunctionCallBackEventArgs Save(dynamic paramsObject, bool autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams = true, string updatedEntryRustParamName = "updated_entry", string originalEntryHashRustParamName = "original_action_hash", bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
Parameter | Description |
---|---|
paramsObject | The dynamic data object containing the params you wish to pass to the Create/Update zome function via the CallZomeFunction method. NOTE: You do not need to pass this in unless you have a need, if you call one of the overloads that do not have this parameter HoloNETEntryBaseClass will automatically generate this object from any properties in your class that contain the HolochainFieldName attribute. |
customDataKeyValuePairs | This is a optional dictionary containing keyvalue pairs of custom data you wish to inject into the params that are sent to the zome function. |
holochainFieldsIsEnabledKeyValuePairs | This is a optional dictionary containing keyvalue pairs to allow properties that contain the HolochainFieldName to be omitted from the data sent to the zome function. The key (case senstive) needs to match a property that has the HolochainFieldName attribute. |
cachePropertyInfos | This is an optional param, set this to true (default) if you want HoloNET to cache the property info's for the Entry Data Object (this can reduce the slight overhead used by reflection). |
autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams | Set this to true if you want HoloNET to auto-generate the updatedEntry object and originalEntryHash params that are passed to the update zome function in your hApp rust code. If this is false then only the paramsObject will be passed to the zome update function and you will need to manually set these object/params yourself. This is an optional param that defaults to true. NOTE: This is set to true for the Save overloads that do not take a paramsobject (use reflection). |
updatedEntryRustParamName | This is the name of the updated entry object param that is in your rust hApp zome update function. This defaults to 'updated_entry'. This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams param is false. |
originalEntryHashRustParamName | This is the name of the original entry/action hash param that is in your rust hApp zome update function. This defaults to 'original_action_hash'. This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams param is false. |
useReflectionToMapKeyValuePairResponseOntoEntryDataObject | This is an optional param, set this to true (default) to map the data returned from the Holochain Conductor onto the Entry Data Object that extends this base class (HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass). This will have a very small performance overhead but means you do not need to do the mapping yourself from the ZomeFunctionCallBackEventArgs.KeyValuePair. |
Below is an example of how to override the SaveAsync in a class that extends the HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass:
public override Task<ZomeFunctionCallBackEventArgs> SaveAsync(Dictionary<string, string> customDataKeyValuePair = null, Dictionary<string, bool> holochainFieldsIsEnabledKeyValuePair = null, bool cachePropertyInfos = true, useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
{
//Example of how to disable various holochain fields/ properties so the data is omitted from the data sent to the zome function.
if (holochainFieldsIsEnabledKeyValuePair == null)
holochainFieldsIsEnabledKeyValuePair = new Dictionary<string, bool>();
holochainFieldsIsEnabledKeyValuePair["DOB"] = false;
holochainFieldsIsEnabledKeyValuePair["Email"] = false;
//Below is an example of how you can send custom data to the zome function:
if (customDataKeyValuePair == null)
customDataKeyValuePair = new Dictionary<string, string>();
customDataKeyValuePair["dynamic data"] = "dynamic";
customDataKeyValuePair["some other data"] = "data";
return base.SaveAsync(customDataKeyValuePair, holochainFieldsIsEnabledKeyValuePair, cachePropertyInfos, useReflectionToMapKeyValuePairResponseOntoEntryDataObject);
}
This example is taken from the Avatar class in the Single Class Example folder in the HoloNET Test Harness.
For additional clarity of what the autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams param does please view an exert from the SaveAsync method on HoloNETEntryBaseClass:
if (string.IsNullOrEmpty(EntryHash))
result = await HoloNETClient.CallZomeFunctionAsync(ZomeName, ZomeCreateEntryFunction, paramsObject);
else
{
if (autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams)
{
dynamic updateParamsObject = new ExpandoObject();
ExpandoObjectHelpers.AddProperty(updateParamsObject, originalEntryHashRustParamName, HoloNETClient.ConvertHoloHashToBytes(EntryHash));
ExpandoObjectHelpers.AddProperty(updateParamsObject, updatedEntryRustParamName, paramsObject);
result = await HoloNETClient.CallZomeFunctionAsync(ZomeName, ZomeUpdateEntryFunction, updateParamsObject);
}
else
result = await HoloNETClient.CallZomeFunctionAsync(ZomeName, ZomeUpdateEntryFunction, paramsObject);
}
NOTE: We would recommend you leave this param as well as the others on their defaults unless you have a specefic use case where you need to override any of the default behaviour.
Delete
This method will soft delete the Holochain entry (the previous version can still be retrieved). This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeDeleteEntryFunction
or property ZomeDeleteEntryFunction. It then updates the HoloNET Entry Data Object with the response received from the Holochain Conductor and then finally raises the OnDeleted event.
NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info...

Parameter | Description |
---|---|
entryHash | The hash of the Holochain Entry you wish to delete. For the overloads that do not take the entryHash as a paramater it will use the EntryHash property. |
customFieldToDeleteByValue | The custom field value to delete by (if you do not wish to delete by the EntryHash). |
customFieldToDeleteByKey | The custom field key to delete by (if you do not wish to delete by the EntryHash). NOTE: This field is only needed if you also pass in a customDataKeyValuePairs dictionary otherwise only the customFieldToDeleteByValue is required. If no customDataKeyValuePairs is passed in then this field (customFieldToDeleteByKey) will be ignored. |
customDataKeyValuePairs | This is an optional param where a dictionary containing additional params (KeyValue Pairs) can be passed to the zome function. If this is passed in then the entryHash or customFieldToDeleteByValue will automatically be added to the new params with key entry_hash (make sure your hApp zome function is expecting this name) or customFieldToDeleteByKey. |
useReflectionToMapKeyValuePairResponseOntoEntryDataObject | This is an optional param, set this to true (default) to map the data returned from the Holochain Conductor onto the Entry Data Object that extends this base class (HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass). This will have a very small performance overhead but means you do not need to do the mapping yourself from the ZomeFunctionCallBackEventArgs.KeyValuePair. |
Close
Will close this HoloNET Entry and then shutdown its internal HoloNET instance (if one was not passed in) and its current connetion to the Holochain Conductor and then shutdown all running Holochain Conductors (if configured to do so) as well as any other tasks to shut HoloNET down cleanly. This method calls the ShutdownHoloNET method internally. Once it has finished shutting down HoloNET it will raise the OnClosed event. You can specify if HoloNET should wait until it has finished disconnecting and shutting down the conductors before returning to the caller or whether it should return immediately and then use the OnDisconnected, OnHolochainConductorsShutdownComplete & OnHoloNETShutdownComplete events to notify the caller.
NOTE:: This applies ONLY for the non async version: Unlike the async version, the non async version will not wait until HoloNET disconnects & shutsdown any Holochain Conductors before it returns to the caller. It will later raise the Disconnected, HolochainConductorsShutdownComplete & HoloNETShutdownComplete events. If you wish to wait for HoloNET to disconnect and shutdown the conductors(s) before returning then please use CloseAsync instead. It will also not contain any Holochain conductor shutdown stats and the HolochainConductorsShutdownEventArgs property will be null (Only the CloseAsync version contains this info).
public virtual async Task<HoloNETShutdownEventArgs> CloseAsync(DisconnectedCallBackMode disconnectedCallBackMode = DisconnectedCallBackMode.WaitForHolochainConductorToDisconnect, ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
public virtual HoloNETShutdownEventArgs Close(ShutdownHolochainConductorsMode shutdownHolochainConductorsMode = ShutdownHolochainConductorsMode.UseConfigSettings)
Parameter | Description |
---|---|
disconnectedCallBackMode | If this is set to WaitForHolochainConductorToDisconnect (default) then it will await until it has disconnected before returning to the caller, otherwise (it is set to UseCallBackEvents ) it will return immediately and then raise the OnDisconnected once it is disconnected. |
shutdownHolochainConductorsMode | Once it has successfully disconnected it will automatically call the ShutDownAllHolochainConductors method if the shutdownHolochainConductorsMode flag (defaults to UseConfigSettings ) is not set to DoNotShutdownAnyConductors . Other values it can be are 'ShutdownCurrentConductorOnly' or 'ShutdownAllConductors'. Please see the ShutDownConductors method below for more detail. |
WaitTillHoloNETInitializedAsync
This mehod will call the WaitTillReadyForZomeCallsAsync method on the HoloNET Client.
public async Task<ReadyForZomeCallsEventArgs> WaitTillHoloNETInitializedAsync()
<a name="HoloNETEntryBaseClassProperties"></a>
Properties
The HoloNETEntryBaseClass has the following properties:
Property | Description | |
---|---|---|
HoloNETClient | This is a reference to the internal instance of the HoloNET Client (either the one passed in through a constructor or one created internally.) | |
IsInitializing | This will return true whilst HoloNETEntryBaseClass and it's internal HoloNET client is initializing. The Initialize method will begin the initialization process. This will also call the Connect and RetrieveAgentPubKeyAndDnaHash methods on the HoloNET client. Once the HoloNET client has successfully connected to the Holochain Conductor, retrieved the AgentPubKey & DnaHash & then raised the OnReadyForZomeCalls event it will raise the OnInitialized event. See also the IsInitialized property. | |
IsInitialized | This will return true once HoloNETEntryBaseClass and it's internal HoloNET client have finished initializing and the OnInitialized event has been raised. See also the IsInitializing property and the Initialize method. | |
EntryData | The entry dictionary containing the actual user data (after it has been processed/decoded) retrived from the zome call. This also includes a EntryDataObject property containing a dynamic data object that is mapped to the dictionary using the optional type (or actual data object) passed into the CallZomeFunctionAsync method. This effectively maps the rust data struct properties contained in the hApp to your C# data object/class. It also contains additional metadata returned from the Holochain Conductor. You will not normally need to use this property because HoloNETEntryBaseClass will automatically map all the properties and relevant meta data to the properties defined in any class that extends HoloNETEntryBaseClass. It does however, contain additional metadata that may be useful to the developer. | |
EntryHash | This is the hash generated by the Holochain Conductor for the Holochain Entry that the HoloNETEntryBaseClass maps onto. This will be empty until after the first call to the Save method. | |
PreviousVersionEntryHash | This is the previous EntryHash before the last call of the Save method. | |
ZomeName | This is the name of the rust zome in your hApp that this instance of the HoloNETEntryBaseClass maps onto. You can set this either through this property or through one of the constructors. | |
ZomeCreateEntryFunction | This is the name of the rust zome function in your hApp that will be used to create new Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. This will be used by the Save method. You can set this either through this property or through one of the constructors. | |
ZomeLoadEntryFunction | This is the name of the rust zome function in your hApp that will be used to load existing Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. This will be used by the Load method. You can set this either through this property or through one of the constructors. | |
ZomeUpdateEntryFunction | This is the name of the rust zome function in your hApp that will be used to update existing Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. This will be used by the Save method. You can set this either through this property or through one of the constructors. | |
ZomeDeleteEntryFunction | This is the name of the rust zome function in your hApp that will be used to delete existing Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. This will be used by the Delete method. You can set this either through this property or through one of the constructors. |
HoloNETClient
This is a reference to the internal instance of the HoloNET Client (either the one passed in through a constructor or one created internally.)
IsInitializing
This will return true whilst HoloNETEntryBaseClass and it's internal HoloNET client is initializing. The Initialize method will begin the initialization process. This will also call the Connect and RetrieveAgentPubKeyAndDnaHash methods on the HoloNET client. Once the HoloNET client has successfully connected to the Holochain Conductor, retrieved the AgentPubKey & DnaHash & then raised the OnReadyForZomeCalls event it will raise the OnInitialized event. See also the IsInitialized property. |
IsInitialized
This will return true once HoloNETEntryBaseClass and it's internal HoloNET client have finished initializing and the OnInitialized event has been raised. See also the IsInitializing property and the Initialize method.
EntryData
The EntryData property contains the following sub-properties:
Parameter | Description |
---|---|
Bytes | Contains the raw bytes returned from the Holochain Conductor for the data entry. |
BytesString | Contains the raw bytes returned from the Holochain Conductor for the data entry as a comma delimited string, which can be used for logging/debugging etc. |
Entry | Contains the keyvalue pair dictionary for the entry data returned from the conductor. |
EntryDataObject | If the type of the entry data object (entryDataObjectTypeReturnedFromZome param) or the actual data object (entryDataObjectReturnedFromZome param) is passed into one of the CallZomeFunctionAsync overloads then HoloNET will attempt to map the hApp rust properties (contained in the struct) to the C# type/class/object passed in and then pass the newly created dynamic object (will update the existing data object if entryDataObjectReturnedFromZome param is used) back to the caller via this property. It will also update the actual data object (by ref) if entryDataObjectReturnedFromZome param is used. |
Author | The author of the entry (AgentPubKey on their device). |
Hash | The true EntryHash (is Hash in the meta data returned from the Holochain Conductor). |
EntryHash | This is a metadata property called EntryHash returned from the Holochain Conductor but currently it is unknown what this is? Still investigating... If anyone know's what this is please get in touch and let us know, thank you! 😃 |
PreviousHash | The previous Hash (EntryHash). |
Signature | The signature of the entry. |
Timestamp | The Unix timestamp (returned from the Holochain Conductor). |
DateTime | Standard .NET DateTime converted from the Unix timestamp (returned from the Holochain Conductor). |
Type | Can be Create/Update/Delete. |
EntryType | Can be App, maybe other types? |
ActionSequence | The Action Sequence for this entry. |
OriginalActionAddress | Is the original Hash for the entry. |
OriginalEntryAddress | Is the original EntryHash for the entry. |
NOTE: Please see the OnZomeFunctionCallBack event handler to see examples of how to use and access this property along with how to map your custom c# data object to the rust properties in your hApp when using the CallZomeFunction method. When using any class that extends the HoloNETEntryBaseClass this mapping is automatic and built in.
EntryHash
This is the hash generated by the Holochain Conductor for the Holochain Entry that the HoloNETEntryBaseClass maps onto. This will be empty until after the first call to the Save method.
PreviousVersionEntryHash
This is the previous EntryHash before the last call of the Save method.
Version
This is the current version of the HolochainEntry. Each time it is saved with the Save method it will be incremented. NOTE: You will need to ensure you add a corresponding property in the rust entry struct for your hApp (pub version: i32), which will then map to this property.
ZomeName
This is the name of the rust zome in your hApp that this instance of the HoloNETEntryBaseClass maps onto. You can set this either through this property or through one of the constructors.
ZomeCreateEntryFunction
This is the name of the rust zome function in your hApp that will be used to create new Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. You can set this either through this property or through one of the constructors.
ZomeLoadEntryFunction
This is the name of the rust zome function in your hApp that will be used to load existing Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. You can set this either through this property or through one of the constructors.
ZomeUpdateEntryFunction
This is the name of the rust zome function in your hApp that will be used to update existing Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. You can set this either through this property or through one of the constructors.
ZomeDeleteEntryFunction
This is the name of the rust zome function in your hApp that will be used to delete existing Holochain enties that this instance of the HoloNETEntryBaseClass maps onto. You can set this either through this property or through one of the constructors.
HoloNETAuditEntryBaseClass
This is very similar to HoloNETEntryBaseClass because it extends it by adding auditing capabilities.
Here is a simple example of how to use it:
/// <summary>
/// This example creates its own internal instance of the HoloNETClient, you should only use this if you will be extending only one HoloNETAuditEntryBaseClass/HoloNETEntryBaseClass otherwise use the Multiple Class Example.
/// </summary>
public class Avatar : HoloNETAuditEntryBaseClass
{
public Avatar() : base("oasis", "get_entry_avatar", "create_entry_avatar", "update_entry_avatar", "delete_entry_avatar") { }
public Avatar(HoloNETConfig holoNETConfig) : base("oasis", "get_entry_avatar", "create_entry_avatar", "update_entry_avatar", "delete_entry_avatar", holoNETConfig) { }
[HolochainFieldName("first_name")]
public string FirstName { get; set; }
[HolochainFieldName("last_name")]
public string LastName { get; set; }
[HolochainFieldName("email")]
public string Email { get; set; }
[HolochainFieldName("dob")]
public DateTime DOB { get; set; }
}
And here is the rust code in the hApp that this maps onto:
#[hdk_entry_helper]
#[derive(Clone)]
pub struct Avatar {
pub id: String,
pub first_name: String,
pub last_name: String,
pub email: String,
pub dob: String,
pub created_date: String,
pub created_by: String,
pub modified_date: String,
pub modified_by: String,
pub deleted_date: String,
pub deleted_by: String,
pub is_active: bool,
pub version: i32
}
#[derive(Serialize, Deserialize, Debug)]
pub struct UpdateEntryAvatarInput {
original_action_hash: ActionHash,
updated_entry: Avatar
}
#[hdk_entry_defs]
#[unit_enum(UnitEntryTypes)]
pub enum EntryTypes {
#[entry_def()]
Avatar(Avatar),
}
#[hdk_extern]
pub fn create_entry_avatar(avatar: Avatar) -> ExternResult<ActionHash> {
create_entry(&EntryTypes::Avatar(avatar.clone()))
}
#[hdk_extern]
pub fn get_entry_avatar(action_hash: ActionHash) -> ExternResult<Option<Record>> {
get(action_hash, GetOptions::default())
}
#[hdk_extern]
pub fn update_entry_avatar(input: UpdateEntryAvatarInput) -> ExternResult<ActionHash>
{
update_entry(input.original_action_hash, &input.updated_entry)
}
#[hdk_extern]
pub fn delete_entry_avatar(action_hash: ActionHash) -> ExternResult<ActionHash> {
delete_entry(action_hash)
}
NOTE: Each property that you wish to have mapped to a property/field in your rust code needs to have the HolochainFieldName attribute applied to it specifying the name of the field in your rust struct that is to be mapped to this c# property.
NOTE: You will note that the rust code for using the HoloNETAuditEntryBaseClass is the same as HoloNETEntryBaseClass except it adds the audit fields to the Avatar struct.
NOTE: This is a preview of some of the advanced functionality that will be present in the upcoming .NET HDK Low Code Generator, which generates dynamic rust and c# code from your metadata freeing you to focus on your amazing business idea and creativity rather than worrying about learning Holochain, Rust and then getting it to all work in Windows and with C#. HAppy Days! 😉

Parameter | Description |
---|---|
isVersionTrackingEnabled | Set this to true if you wish to enable Version Tracking (you will need to make sure your hApp rust code has the version field added to your entry struct). |
isAuditTrackingEnabled | Set this to true if you wish to enable Audit Tracking (the AuditEntries property will be updated every time the entry/object is saved or deleted). |
isAuditAgentCreateModifyDeleteFieldsEnabled | Set this to true if you wish to update the CreatedDate, CreatedBy, ModifiedDate, ModifiedBy, DeletedData & DeletedBy properties each time the entry/object is saved or deleted (you will need to make sure your hApp rust code has the created_date, created_by, modified_date, modified_by, deleted_date & deleted_by fields in your entry struct). |

<a name="HoloNETAuditEntryBaseClassEvents"></a>
Events
Please see Events for HoloNETEntryBaseClass because they share the same events.
<a name="HoloNETAuditEntryBaseClassMethods"></a>
Methods
The HoloNETAuditEntryBaseClass shares the same Methods as HoloNETEntryBaseClass but also has these differences:
Method | Description |
---|---|
Load | This method will load the Holochain entry from the Holochain Conductor using either the EntryHash property or entryHash param passed into one of the overloads for this method. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeLoadEntryFunction or property ZomeLoadEntryFunction and then maps the data returned from the zome call onto your data object. It will then raise the OnLoaded event. NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info... |
Save | This method will save the Holochain entry to the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeCreateEntryFunction or property ZomeCreateEntryFunction if it is a new entry (empty object) or the zomeUpdateEntryFunction param and ZomeUpdateEntryFunction property if it's an existing entry (previously saved object containing a valid value for the EntryHash property). Once it has saved the entry it will then update the EntryHash property with the entry hash returned from the zome call/conductor. The PreviousVersionEntryHash property is also set to the previous EntryHash (if there is one). Once it has finished saving and got a response from the Holochain Conductor it will raise the OnSaved event. NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info... NOTE: The parmeterless overload will automatically extrct the properties that need saving (contain the HolochainFieldName attribute). This method uses reflection so has a tiny performance overhead (negligbale), but if you need the extra nanoseconds use the other Save overload passing in your own params object. |
<a name="HoloNETAuditEntryBaseClassLoad"></a>
Load
This method will load the Holochain entry from the Holochain Conductor using either the EntryHash property or entryHash
param passed into one of the overloads for this method. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeLoadEntryFunction
or property ZomeLoadEntryFunction
and then maps the data returned from the zome call onto your data object. It will then raise the OnLoaded event.
NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info...
public virtual async Task<ZomeFunctionCallBackEventArgs> LoadAsync(string entryHash, int version = 0, Dictionary<string, string> customDataKeyValuePairs = null, useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
public virtual ZomeFunctionCallBackEventArgs Load(string entryHash, int version = 0, Dictionary<string, string> customDataKeyValuePairs = null, useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)

public virtual ZomeFunctionCallBackEventArgs Load(string customFieldToLoadByValue, string customFieldToLoadByKey = "", int version = 0, Dictionary<string, string> customDataKeyValuePairs = null, bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
Parameter | Description |
---|---|
entryHash | The hash of the Holochain Entry you wish to load. For the overloads that do not take the entryHash as a paramater it will use the EntryHash property. |
customFieldToLoadByValue | The custom field value to load by (if you do not wish to load by the EntryHash). |
customFieldToLoadByKey | The custom field key to load by (if you do not wish to load by the EntryHash). NOTE: This field is only needed if you also pass in a customDataKeyValuePairs dictionary otherwise only the customFieldToLoadByValue is required. If no customDataKeyValuePairs is passed in then this field (customFieldToLoadByKey) will be ignored. |
version | This is the version of the Holochain Entry you wish to return. The default is 0 which means the latest will be retreived. NOTE: The version will be added to the customDataKeyValuePairs dictionary with key 'version'. |
customDataKeyValuePairs | This is an optional param where a dictionary containing additional params (KeyValue Pairs) can be passed to the zome function. If this is passed in then the entryHash or customFieldToLoadByValue will automatically be added to the new params with key entry_hash (make sure your hApp zome function is expecting this name) or customFieldToLoadByKey. |
useReflectionToMapKeyValuePairResponseOntoEntryDataObject | This is an optional param, set this to true (default) to map the data returned from the Holochain Conductor onto the Entry Data Object that extends this base class (HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass). This will have a very small performance overhead but means you do not need to do the mapping yourself from the ZomeFunctionCallBackEventArgs.KeyValuePair. |
<a name="HoloNETAuditEntryBaseClassSave"></a>
Save
This method will save the Holochain entry to the Holochain Conductor. This calls the CallZomeFunction on the HoloNET client passing in the zome function name specified in the constructor param zomeCreateEntryFunction
or property ZomeCreateEntryFunction if it is a new entry (empty object) or the zomeUpdateEntryFunction
param and ZomeUpdateEntryFunction property if it's an existing entry (previously saved object containing a valid value for the EntryHash property). Once it has saved the entry it will then update the EntryHash property with the entry hash returned from the zome call/conductor. The PreviousVersionEntryHash property is also set to the previous EntryHash (if there is one). Once it has finished saving and got a response from the Holochain Conductor it will raise the OnSaved event.
NOTE: The overloads that do not have the paramsObject param will automatically extrct the properties that need saving (contain the HolochainFieldName attribute). This method uses reflection so has a tiny performance overhead (negligbale), but if you need the extra nanoseconds use the other Save overload passing in your own params object.
NOTE: The corresponding rust Holochain Entry in your hApp will need to have the same properties contained in your class and have the correct mappings using the HolochainFieldName attribute. Please see HoloNETEntryBaseClass for more info...
public virtual async Task<ZomeFunctionCallBackEventArgs> SaveAsync(Dictionary<string, string> customDataKeyValuePairs = null, Dictionary<string, bool> holochainFieldsIsEnabledKeyValuePairs = null, bool cachePropertyInfos = true, bool useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)

Parameter | Description |
---|---|
paramsObject | The dynamic data object containing the params you wish to pass to the Create/Update zome function via the CallZomeFunction method. NOTE: You do not need to pass this in unless you have a need, if you call one of the overloads that do not have this parameter HoloNETEntryBaseClass will automatically generate this object from any properties in your class that contain the HolochainFieldName attribute. |
customDataKeyValuePairs | This is a optional dictionary containing keyvalue pairs of custom data you wish to inject into the params that are sent to the zome function. |
holochainFieldsIsEnabledKeyValuePairs | This is a optional dictionary containing keyvalue pairs to allow properties that contain the HolochainFieldName to be omitted from the data sent to the zome function. The key (case senstive) needs to match a property that has the HolochainFieldName attribute. |
cachePropertyInfos | This is an optional param, set this to true (default) if you want HoloNET to cache the property info's for the Entry Data Object (this can reduce the slight overhead used by reflection). |
autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams | Set this to true if you want HoloNET to auto-generate the updatedEntry object and originalEntryHash params that are passed to the update zome function in your hApp rust code. If this is false then only the paramsObject will be passed to the zome update function and you will need to manually set these object/params yourself. This is an optional param that defaults to true. NOTE: This is set to true for the Save overloads that do not take a paramsobject (use reflection). |
updatedEntryRustParamName | This is the name of the updated entry object param that is in your rust hApp zome update function. This defaults to 'updated_entry'. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams param is false. |
originalEntryHashRustParamName | This is an optional param, set this to true (default) to map the data returned from the Holochain Conductor onto the Entry Data Object that extends this base class (HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass). This will have a very small performance overhead but means you do not need to do the mapping yourself from the ZomeFunctionCallBackEventArgs.KeyValuePair. |
addAuditInfoToParams | Set this to true (default) to automatically add the additional audit data such as created_date, created_by, modifed_date, modified_by, deleted_date & deleted_by to the paramsObject passed in. This is an optional param. |
addVersionToParams | Set this to true (default) to automatically add the version number to the paramsObject passed in. This is an optional param. |
createdDateRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param CreatedBy (default is created_by). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addAuditInfoToParams param is false. |
createdByRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param CreatedDate (default is created_date). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addAuditInfoToParams param is false. |
modifiedDateRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param ModifedBy (default is modified_by). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addAuditInfoToParams param is false. |
modifiedByRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param ModifiedDate (default is modified_date). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addAuditInfoToParams param is false. |
deletedDateRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param DeletedBy (default is deleted_by). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addAuditInfoToParams param is false. |
deletedByRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param DeletedDate (default is deleted_date). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addAuditInfoToParams param is false. |
versionRustParamName | Set this to the name of the rust param in your hApp zome update function for the audit param Version (default is version). This is an optional param. NOTE: Whatever name that is given here needs to match the same name in your zome update function. NOTE: This param is ignored if the addVersionToParams param is false. |
useReflectionToMapKeyValuePairResponseOntoEntryDataObject | This is an optional param, set this to true (default) to map the data returned from the Holochain Conductor onto the Entry Data Object that extends this base class (HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass). This will have a very small performance overhead but means you do not need to do the mapping yourself from the ZomeFunctionCallBackEventArgs.KeyValuePair. |
Below is an example of how to override the SaveAsync in a class that extends the HoloNETEntryBaseClass or HoloNETAuditEntryBaseClass:
public override Task<ZomeFunctionCallBackEventArgs> SaveAsync(Dictionary<string, string> customDataKeyValuePair = null, Dictionary<string, bool> holochainFieldsIsEnabledKeyValuePair = null, bool cachePropertyInfos = true, useReflectionToMapKeyValuePairResponseOntoEntryDataObject = true)
{
//Example of how to disable various holochain fields/ properties so the data is omitted from the data sent to the zome function.
if (holochainFieldsIsEnabledKeyValuePair == null)
holochainFieldsIsEnabledKeyValuePair = new Dictionary<string, bool>();
holochainFieldsIsEnabledKeyValuePair["DOB"] = false;
holochainFieldsIsEnabledKeyValuePair["Email"] = false;
//Below is an example of how you can send custom data to the zome function:
if (customDataKeyValuePair == null)
customDataKeyValuePair = new Dictionary<string, string>();
customDataKeyValuePair["dynamic data"] = "dynamic";
customDataKeyValuePair["some other data"] = "data";
return base.SaveAsync(customDataKeyValuePair, holochainFieldsIsEnabledKeyValuePair, cachePropertyInfos, useReflectionToMapKeyValuePairResponseOntoEntryDataObject);
}
This example is taken from the Avatar class in the Single Class Example folder in the HoloNET Test Harness.
For additional clarity of what the autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams param does please view an exert from the SaveAsync method on HoloNETEntryBaseClass:
if (string.IsNullOrEmpty(EntryHash))
result = await HoloNETClient.CallZomeFunctionAsync(ZomeName, ZomeCreateEntryFunction, paramsObject);
else
{
if (autoGeneratUpdatedEntryObjectAndOriginalEntryHashRustParams)
{
dynamic updateParamsObject = new ExpandoObject();
ExpandoObjectHelpers.AddProperty(updateParamsObject, originalEntryHashRustParamName, HoloNETClient.ConvertHoloHashToBytes(EntryHash));
ExpandoObjectHelpers.AddProperty(updateParamsObject, updatedEntryRustParamName, paramsObject);
result = await HoloNETClient.CallZomeFunctionAsync(ZomeName, ZomeUpdateEntryFunction, updateParamsObject);
}
else
result = await HoloNETClient.CallZomeFunctionAsync(ZomeName, ZomeUpdateEntryFunction, paramsObject);
}
NOTE: We would recommend you leave this param as well as the others on their defaults unless you have a specefic use case where you need to override any of the default behaviour.
NOTE: You will notice that currently you can only edit the audit rust param names for the non reflective versions (that take a paramsObject) because the reflective versions (that use reflection to dynamically generate the paramsObject for you) currently have no way for you to rename the audit param rust names. This will be addressed in a future version...
<a name="HoloNETAuditEntryBaseClassProperties"></a>
Properties
The HoloNETAuditEntryBaseClass shares the same Properties as HoloNETEntryBaseClass but also has these:
Property | Description |
---|---|
Id | This is a unique ID (GUID) given to the entry which is consistent across multiple versions. |
CreatedDate | The date that the entry was created. |
CreatedBy | The AgentID of the agent/user that created it. |
ModifiedDate | The date that the entry was last modified. |
ModifiedBy | The AgentID of the agent/user that last modified it. |
DeletedDate | The date that the entry was deleted. |
DeletedBy | The AgentID of the agent/user that deleted it. |
IsActive | A boolean flag that determines whether the entry is currently active or not. |
AuditEntries | This contains a collection of audit enties that allow you to track every action that was taken on the Holochain Entry that this instance of the HoloNETAuditEntryBaseClass maps onto. Each audit entry contains the EntryHash, DateTime & the Type (Create, Modify or Delete). |
Version | This is the current version of the HolochainEntry. Each time it is saved with the Save method it will be incremented. NOTE: You will need to ensure you add a corresponding property in the rust entry struct for your hApp (pub version: i32), which will then map to this property. |
IsVersionTrackingEnabled | Set this to true if you wish to enable Version Tracking (you will need to make sure your hApp rust code has the version field added to your entry struct). |
IsAuditTrackingEnabled | Set this to true if you wish to enable Audit Tracking (the AuditEntries property will be updated every time the entry/object is saved or deleted). |
IsAuditAgentCreateModifyDeleteFieldsEnabled | Set this to true if you wish to update the CreatedDate, CreatedBy, ModifiedDate, ModifiedBy, DeletedData & DeletedBy properties each time the entry/object is saved or deleted (you will need to make sure your hApp rust code has the created_date, created_by, modified_date, modified_by, deleted_date & deleted_by fields in your entry struct). |
Id
This is a unique ID (GUID) given to the entry which is consistent across multiple versions.
CreatedDate
The date that the entry was created.
ModifiedDate
The date that the entry was last modified.
ModifiedBy
The AgentID of the agent/user that last modified it.
DeletedDate
The date that the entry was deleted.
IsActive
A boolean flag that determines whether the entry is currently active or not.
AuditEntries
This contains a collection of audit enties that allow you to track every action that was taken on the Holochain Entry that this instance of the HoloNETAuditEntryBaseClass maps onto. Each audit entry contains the EntryHash, DateTime & the Type (Create, Modify or Delete). |
Version
This is the current version of the HolochainEntry. Each time it is saved with the Save method it will be incremented. NOTE: You will need to ensure you add a corresponding property in the rust entry struct for your hApp (pub version: i32), which will then map to this property.
IsVersionTrackingEnabled
Set this to true if you wish to enable Version Tracking (you will need to make sure your hApp rust code has the version field added to your entry struct).
IsAuditTrackingEnabled
Set this to true if you wish to enable Audit Tracking (the AuditEntries property will be updated every time the entry/object is saved or deleted).
IsAuditAgentCreateModifyDeleteFieldsEnabled
Set this to true if you wish to update the CreatedDate, CreatedBy, ModifiedDate, ModifiedBy, DeletedData & DeletedBy properties each time the entry/object is saved or deleted (you will need to make sure your hApp rust code has the created_date, created_by, modified_date, modified_by, deleted_date & deleted_by fields in your entry struct).
Test Harness
You can find the Test Harness here:
NextGenSoftware.Holochain.HoloNET.Client.TestHarness
Read more on how to use the Test Harness here.
More to come soon...
HoloOASIS
HoloOASIS
uses the HoloNETClient to implement a Storage Provider (IOASISStorage) for the OASIS System. It will soon also implement a Network Provider (IOASISNET)
for the OASIS System that will leverage Holochain to create it's own private de-centralised distributed network called ONET
(as seen on the OASIS Architecture Diagram).
This is a good example to see how to use HoloNETClient in a real world game/platform (OASIS/Our World).
Check out the full documentation here.
HoloUnity
We will soon be creating a Asset for the Unity Asset Store that will include HoloNET along with Unity wrappers and examples of how to use HoloNET inside Unity.
In the codebase you will find a project called NextGenSoftware.OASIS.API.FrontEnd.Unity, which shows how the AvatarManager
found inside the OASIS API Core
(NextGenSoftware.OASIS.API.Core) is used. When you instantiate the AvatarManager
you inject into a Storage Provider that implements the IOASISStorage interface. Currently the only provider implemented is the HoloOASIS Provider.
The actual Our World Unity code is not currently stored in this repo due to size restrictions but we may consider using GitHub LFS (Large File Storage) later on. We are also looking at GitLab and other alternatives to see if they allow greater storage capabilities free out of the box (since we are currently working on a very tight budget but you could change that by donating below! 😉 ).
Here is a preview of the OASIS API/Avatar/Karma System... more to come soon... 😉
As with the rest of the project, if you have any suggestions we would love to hear from you! 😃
Using HoloUnity
You start by instantiating the AvatarManager
class found within the NextGenSoftware.OASIS.API.Core project.
// Inject in the HoloOASIS Storage Provider (this could be moved to a config file later so the
// providers can be swapped without having to re-compile.
ProfileManager = new ProfileManager(new HoloOASIS("ws://localhost:8888"));
Now, load the users Profile:
IProfile profile = await ProfileManager.LoadProfileAsync(username, password);
if (profile != null)
{
//TODO: Bind profile info to Unity Avatar UI here.
}
The full code for the screenshot above that loads the users profile/avatar data from holochain and displays it in Unity is below:
using NextGenSoftware.OASIS.API.Core;
using NextGenSoftware.OASIS.API.Providers.HoloOASIS.Unity;
using UnityEngine;
using TMPro;
using System.Threading.Tasks;
public class OASISAvatarManager : MonoBehaviour
{
ProfileManager ProfileManager { get; set; } //If the ProfileManager is going to contain additional business logic not contained in the providers then use this.
public GameObject ProfileUsername;
public GameObject ProfileFullName;
public GameObject ProfileDOB;
public GameObject ProfileEmail;
public GameObject ProfileAddress;
public GameObject ProfileKarma;
public GameObject ProfileLevel;
async Task Start()
{
// Inject in the HoloOASIS Storage Provider (this could be moved to a config file later so the
// providers can be sweapped without having to re-compile.
ProfileManager = new ProfileManager(new HoloOASIS("ws://localhost:8888"));
ProfileManager.OnProfileManagerError += ProfileManager_OnProfileManagerError;
ProfileManager.OASISStorageProvider.OnStorageProviderError += OASISStorageProvider_OnStorageProviderError;
//StorageProvider = new HoloOASIS("ws://localhost:8888");
await LoadProfile();
}
private async Task LoadProfile()
{
//IProfile profile = await ProfileManager.LoadProfileAsync("dellams", "1234");
IProfile profile = await ProfileManager.LoadProfileAsync("QmR6A1gkSmCsxnbDF7V9Eswnd4Kw9SWhuf8r4R643eDshg");
if (profile != null)
{
(ProfileFullName.GetComponent<TextMeshProUGUI>()).text = string.Concat(profile.Title, " ", profile.FirstName, " ", profile.LastName);
(ProfileUsername.GetComponent<TextMeshProUGUI>()).text = profile.Username;
(ProfileDOB.GetComponent<TextMeshProUGUI>()).text = profile.DOB;
(ProfileEmail.GetComponent<TextMeshProUGUI>()).text = profile.Email;
//(ProfileAddress.GetComponent<TextMeshProUGUI>()).text = profile.PlayerAddress;
(ProfileKarma.GetComponent<TextMeshProUGUI>()).text = profile.Karma.ToString();
(ProfileLevel.GetComponent<TextMeshProUGUI>()).text = profile.Level.ToString();
}
}
private void OASISStorageProvider_OnStorageProviderError(object sender, ProfileManagerErrorEventArgs e)
{
Debug.Log("Error occurred in the OASIS Storage Provider: " + e.Reason + ", Error Details: " + e.ErrorDetails);
}
private void ProfileManager_OnProfileManagerError(object sender, ProfileManagerErrorEventArgs e)
{
Debug.Log("Error occurred in the OASIS Profile Manager: " + e.Reason + ", Error Details: " + e.ErrorDetails);
}
// Update is called once per frame
void Update ()
{
}
}
Instead of using the OASIS ProfileManager
to load the data, we could use HoloNETClient directly, the code would then look like this:
using NextGenSoftware.OASIS.API.Core;
//using NextGenSoftware.OASIS.API.Providers.HoloOASIS.Unity;
using NextGenSoftware.Holochain.HoloNET.Client.Unity;
using NextGenSoftware.Holochain.HoloNET.Client.Core;
using UnityEngine;
using TMPro;
using Newtonsoft.Json;
using System.Threading.Tasks;
public class OASISAvatarManager : MonoBehaviour
{
ProfileManager ProfileManager { get; set; } //If the ProfileManager is going to contain additional
business logic not contained in the providers then use this.
public GameObject ProfileUsername;
public GameObject ProfileFullName;
public GameObject ProfileDOB;
public GameObject ProfileEmail;
public GameObject ProfileAddress;
public GameObject ProfileKarma;
public GameObject ProfileLevel;
async Task Start()
{
/*

ProfileManager = new ProfileManager(new HoloOASIS("ws://localhost:8888"));
ProfileManager.OnProfileManagerError += ProfileManager_OnProfileManagerError;
ProfileManager.OASISStorageProvider.OnStorageProviderError += OASISStorageProvider_OnStorageProviderError;
await LoadProfile();

This is how other Unity developers would connect to Holochain using HoloNETClient, because they may not be using the OASIS API.
Of course if they wanted use the OASIS API then the first code listing is how it would be done.

Why this is important & vital to the holochain community
This is really vital and important to the wonderful holochain community because it will open the doors to the massive .NET, Unity and Enterprise sectors bringing the flood of devs, resources and exposure we all really want holochain to see... 😃
So I hope now this has been split out into it's own independent repo and been officially handed over to the holochain open source community others can now jump in and get involved...
What's Next?
Unity Asset
We plan to create a Unity Asset making it easier for other .NET & Unity devs to get involved with Holochain and get building hApps...
We will release this soon...
In the meantime people can make use of this NuGet package.
.NET HDK Low Code Generator
We can then get back to the .NET HDK Low Code Generator (will migrate this repo over to here soon...), this uses HoloNET to call into the dynamically generated rust and c# code. The rust code acts as a DAL (Data Access Layer) and the C# code acts as the BLL (Business Logic Layer). The generated C# code wraps around calls to HoloNET. This code has also already been written and is working with the previous version of Holochain (Redux).
This also allows devs to make use of all the libraries and resources available to them in Rust, .NET & Unity! 😊
So it will not take long to get this working with RSM (we just need to create the RSM CRUD templates for it to use).
Then, we can add the WASM compilation option to allow it to directly generate the .NET code to WASM so it can be used directly with the conductor so it will not even need the rust code at all then! 😃
All of this helps bring yet more C# devs to Holochain who do not have time to learn Rust... 😃
Restore Holochain Support For The OASIS API
Now HoloNET is working again, we can add support for the OASIS API, which will then support Holochain as well as allow bridging to other Blockchains, DB's etc such as Ethereum, EOS, Solana, MongoDB, SQLLite, Neo4j, ThreeFold, ActivityPub, SOLID, IPFS, etc...
We can now complete HOLOOASIS provider meaning we can bridge holochain to all WEB2 (dbs, clouds, etc) and WEB3 blockchains etc giving a easy migration path to holochain.
Read more here:
https://github.com/NextGenSoftwareUK/Our-World-OASIS-API-HoloNET-HoloUnity-And-.NET-HDK
WEB5 STAR Omniverse Interoperable Metaverse Low Code Generator
It also allows the STAR Omniverse Interoperable Metaverse Low Code Generator to dynamically generate rust and c# code allowing people to focus on their idea rather than the lower level implementations and allow them to build metaverse experiences on top of holochain.
The back-end is very close to completion and the front-end is in progress... 😃
This is an evolution of the .NET HDK Low Code Generator so works the same way in that is generates dynamic rust and c# code, except it now also generates moons, planets, stars, galaxies, universes, etc and allows them to run across any blockchain, web2 cloud/db, IPFS, Holochain, etc. Everything that the OASIS API supports. STAR integrates both the .NET HDK (containing HoloNET) as well as the OASIS API and then expresses it in a cyberspace ontology and soooooo much more! 😉 It also allows other metaverses to be integrated in the Open Omniverse, which is the game of and simulation of life...

NuGet Packages:
[NextGenSoftware.Holochain.HoloNET.Client](NextGenSoftware.Holochain.HoloNET.Client)
Lightweight version that does not come with the holochain binaries (hc.exe and holochain.exe).
[NextGenSoftware.Holochain.HoloNET.Client.Embedded](NextGenSoftware.Holochain.HoloNET.Client.Embedded)
This version comes with the holochain binaries (hc.exe and holochain.exe) integrated.
[NextGenSoftware.Holochain.HoloNET.Client.TestHarness](NextGenSoftware.Holochain.HoloNET.Client.TestHarness)
A console test harness for HoloNET Client.
[NextGenSoftware.Holochain.HoloNET.ORM](NextGenSoftware.Holochain.HoloNET.ORM)
The new HoloNET ORM (Object Relational Mapping) allowing very easy & rapid development of hApps. This consists of the HoloNETEntryBase, HoloNETAuditEntryBase, HoloNETCollection and HoloNETObservsableCollection classes. The first two can be extended to create your HoloNET Entry models that map directly onto your data structs in your rust hApp zome code. The second two are collections of these entries. You can then simply call basic CRUD methods on your classes such as Load, Save, Delete, etc making it very quick and easy to build hApps without having to worry about the lower complexities of Holochain or configure and use the Holochain Conductor or API's. You also get change tracking, version control & rollback functionality for free. HoloNET ORM allows any existing .net app/website/game/service to be rapidly and quickly converted to a Holochain hApp with very little code changes (you can simply add a new attribute to the properties in your models) and it will now map to your rust hApp structs (which WEB5 [NextGenSoftware.OASIS.STAR](NextGenSoftware.OASIS.STAR)) can also dynamically generate (it generates rust and c# code). More documentation will be coming soon for this...
[NextGenSoftware.Holochain.HoloNET.ORM.Embedded](NextGenSoftware.Holochain.HoloNET.ORM.Embedded)
This is exactly the same as above except it is using the embedded version of the HoloNET Client so it is integrated with the Holochain Conductor binaries.
[NextGenSoftware.Holochain.HoloNET.Manager](NextGenSoftware.Holochain.HoloNET.Manager)
The new UI to HoloNET Client & HoloNET ORM show casing all of their advanced features. This has many generic backend and UI components that can be used to allow other .net devs to rapidly construct their own .net hApps using HoloNET HDK (HoloNET Client, HoloNET ORM, HoloNET Manager, WEB5 STAR ODK/HDK & HoloNET HyperNET). The HoloNET Manager is currently implemented in WPF but we have plans to port this to Uno, MAUI & OpenSilver meaning it can run natively on Windows, Mac, Linux, TV's, IPads, tablets, android, IOS & web. The work for this has already begun so expect future releases soon...
