  • Consul API: v1.6.10
  • .NET: >= 4.6.1 - .NET Core: >= 2.0.0

Consul.NET is a .NET port of the Go Consul API, but reworked to use .NET idioms such as Tasks/CancellationTokens instead of Goroutines/Channels. The majority of the calls directly track the HTTP API, but this API does have additional functionality that is provided in the Go API, like Locks and Semaphores.


You'll need a running Consul Server on your local machine, or a Consul Agent connected to a Consul Server cluster. To run a local server:

  1. Download a copy of the latest Windows version and unzip it into the Consul.Test folder.
  2. Open a command prompt and cd to the Consul.Test folder.
  3. Run .\consul.exe agent -dev -config-file test_config.json

This creates a 1-server cluster that operates in "dev" mode (does not write data to disk) and listens on

Once Consul is running (you'll see something like ==> Consul agent running!) in your command prompt, then do the following steps in your project.

Add a reference to the Consul library and add a using statement:

using Consul;

Write a function to talk to the KV store:

public static async Task<string> HelloConsul()
    using (var client = new ConsulClient())
        var putPair = new KVPair("hello")
            Value = Encoding.UTF8.GetBytes("Hello Consul")

        var putAttempt = await client.KV.Put(putPair);

        if (putAttempt.Response)
            var getPair = await client.KV.Get("hello");
            return Encoding.UTF8.GetString(getPair.Response.Value, 0,
        return "";

And call it:


You should see Hello Consul in the output of your program. You should also see the following lines in your command prompt, if you're running a local Consul server:

[DEBUG] http: Request /v1/kv/hello (6.0039ms)
[DEBUG] http: Request /v1/kv/hello (0)

The API just went out to Consul, wrote "Hello Consul" under the key "hello", then fetched the data back out and wrote it to your prompt.


All operations are done using a ConsulClient object. First, instantiate a ConsulClient object, which connects to localhost:8500, the default Consul HTTP API port. Once you've got a ConsulClient object, various functionality is exposed as properties under the ConsulClient.

All responses are wrapped in QueryResponse and WriteResponse classes, which provide metadata about the request, like how long it took and the monotonic Consul index when the operation occured.

This API also assumes some knowledge of Consul, including things like blocking queries and consistency modes


The ACL endpoints are used to create, update, destroy, and query Legacy ACL tokens.


The ACLReplication endpoint is used to query the status of ACL Replication.


The Agent endpoints are used to interact with the local Consul agent. Usually, services and checks are registered with an agent which then takes on the burden of keeping that data synchronized with the cluster. For example, the agent registers services and checks with the Catalog and performs anti-entropy to recover from outages.


The AuthMethod endpoints are used to create, update, destroy, and query ACL Auth Methods related to ACL Replication. These are untested and a place-holder for future changes.


The Catalog is the endpoint used to register and deregister nodes, services, and checks. It also provides query endpoints.


The Event endpoints are used to fire new events and to query the available events.


The Health endpoints are used to query health-related information. They are provided separately from the Catalog since users may prefer not to use the optional health checking mechanisms. Additionally, some of the query results from the Health endpoints are filtered while the Catalog endpoints provide the raw entries.


The KV endpoint is used to access Consul's simple key/value store, useful for storing service configuration or other metadata.


The Policy endpoint is used to create, update, delete and read ACL Policies


The Role endpoint is used to create, update, delete and read ACL Roles


The Prepared Query endpoints are used to create, update, destroy, and execute prepared queries. Prepared queries allow you to register a complex service query and then execute it later via its ID or name to get a set of healthy nodes that provide a given service.


The Session endpoints are used to create, destroy, and query sessions.


The Status endpoints are used to get information about the status of the Consul cluster. This information is generally very low level and not often useful for clients.


The Token endpoint is used to create, update, clone, delete and read ACL Tokens

Additional Functions

Functionality based on the Consul guides using the available primitives has been implemented as well, just like the Go API.


Lock is used to implement client-side leader election for a distributed lock. It is an implementation of the Consul Leader Election guide.


Semaphore is used to implement a distributed semaphore using the Consul KV primitives. It is an implementation of the Consul Semaphore guide.

Using with .NET Core and Mono

Both .NET 4.6.1+ and .NET Core 2.0+ are fully supported. Mono is supported on a best-effort basis. It should compile and run happily on Mono but this is not as heavily tested as Microsoft .NET stacks. If you have any issues using the Nuget package or compiling this code with .NET, .NET Core, or Mono, please file a Github issue with details of the problem.


The version number indicates which version of Consul is supported in terms of API features. Since Consul has already a version that consists of three numbers (e.g. 1.6.1), the fourth number is necessary to indicate patch releases of Consul.NET.

Please note that NuGet normalizes version numbers, by omitting zero in the fourth part of the version number. For example version is going to be normalized to 1.6.1. So to avoid problems, versions and tags with zero in the fourth part should be avoided and explicit three part version should be used instead.

Preview versions

Preview builds (aka 'nightly' builds) are distributed using for now. To pull preview versions into your project, use the following NuGet.config file:

<?xml version="1.0" encoding="utf-8"?>
    <add key="consuldotnet-preview" value="" />

Release process

  1. Before making a new release, make sure that the version in Directory.Build.props is up to date.
  2. Head over to the CHANGELOG file. Replace ## Unreleased with the new version name and add an additional ## Unreleased for future changes. Open a PR to update the changelog.
  3. Then, draft a new GitHub Release with a list of changes contained in the new version from the CHANGELOG.
  4. When the draft release is ready, publish it from the GitHub web UI. Be aware, clicking Publish will trigger GitHub to push a new tag (as specified in the new Release entry) which will instruct the CI to build and push a new stable release to
  5. If everything went well, congrats, the new versions should be live on NuGet by now. As a final post-release step, bump the minor version in Directory.Build.props to the next unreleased version number, so that nightly build versioning can benefit.
