NextGenSoftware.ErrorHandling

Structured error handling and the OASISResult pattern — the error propagation backbone of the OASIS Omniverse ecosystem (HoloNET, the OASIS API, STAR ODK, OurWorld).

NuGet License: MIT .NET

Part of the OASIS Omniverse v2.0 Reboot. Visit oasisomniverse.one.

Features

  • OASISResult<T> — null-safe async result type; return success or failure without throwing across API boundaries
  • OASISResult (non-generic) for void operations
  • Structured exception wrappers with rich context metadata
  • Consistent error propagation across all 85+ OASIS API packages and HoloNET
  • Integrates with NextGenSoftware.Logging
  • Multi-target: .NET 8, .NET 9, .NET 10

Installation

dotnet add package NextGenSoftware.ErrorHandling

Quick Start

using NextGenSoftware.ErrorHandling;

public async Task<OASISResult<MyData>> LoadDataAsync(string id)
{
    var result = new OASISResult<MyData>();
    try
    {
        result.Result = await _db.GetAsync(id);
    }
    catch (Exception ex)
    {
        result.Exception = ex;
        result.Message   = $"Failed to load {id}.";
        result.IsError   = true;
    }
    return result;
}

// Call site
var result = await myService.LoadDataAsync("abc123");
if (result.IsError)
    Console.WriteLine($"Error: {result.Message}");
else
    Process(result.Result);

OASISResult Properties

Property Type Description
Result T The returned value on success
IsError bool true if the operation failed
IsWarning bool true if a non-fatal warning occurred
Message string Human-readable error/success message
Exception Exception Underlying exception if any
InnerMessages List<string> Accumulated sub-messages from nested calls

Package Downloads
NextGenSoftware.CLI.Engine

A feature-rich CLI engine providing colour output, animations, progress bars, ASCII art, working-message spinners, formatted tables, and more — the CLI backbone of the entire OASIS Omniverse ecosystem. Used internally by HoloNET, the OASIS API (85+ packages), STAR ODK, and OurWorld. Easy to drop into any .NET app needing rich CLI output. Part of the OASIS Omniverse at https://oasisomniverse.one -- Source: https://github.com/NextGenSoftwareUK/NextGenSoftware-Libraries
NextGenSoftware.Logging

A flexible, pluggable logging library with a clean ILogger/ILogProvider abstraction used across the entire NextGen Software ecosystem (OASIS, HoloNET, STAR). Supports multiple simultaneous log providers -- console, file, NLog, and custom implementations. Configurable log levels, formatting, and async log dispatch. Part of the OASIS Omniverse ecosystem at https://oasisomniverse.one -- Source: https://github.com/NextGenSoftwareUK/NextGenSoftware-Libraries
NextGenSoftware.WebSocket

A lightweight, high-performance WebSocket client library with a clean event-driven API (OnConnected, OnDisconnected, OnDataReceived, OnError, and more). Used internally by HoloNET (Holochain .NET client) and the OASIS ecosystem. Supports .NET 8, .NET 9, and .NET 10. Easy to embed in any .NET app needing reliable, long-lived WebSocket connections. Part of the OASIS Omniverse ecosystem at https://oasisomniverse.one -- Source: https://github.com/NextGenSoftwareUK/NextGenSoftware-Libraries
NextGenSoftware.OASIS.Common

The shared foundation layer for the entire OASIS ecosystem -- OASISResult/OASISResultCollectionWithPagination result types, shared constants, extension methods, cross-cutting error handling, and utility helpers relied upon by every other OASIS NuGet package. A transitive dependency of all OASIS packages. Part of the OASIS Omniverse at https://oasisomniverse.one

## v2.0.4

- NextGenSoftware.Logging: file logging no longer slows down as log files accumulate (it listed and checked every file in the log folder on every line, so apps that log a lot - like HoloNET, which logs on its WebSocket thread - timed out); writes are serialised in-process; only MaxLogFiles (default 50) log files are kept. Faulty log providers can't break logging (snapshot of providers).
- NextGenSoftware.WebSocket: the receive loop runs on the thread pool (it inherited the caller's SynchronizationContext, so WPF/WinForms apps handled every message on the UI thread and froze on any blocking call); TrySendRawDataAsync reports send failures instead of throwing.
- All NextGenSoftware libraries bumped to 2.0.4 together.
