Raisin.EventSystem

Lightweight, thread-safe event bus for .NET 8 applications with automatic UI thread marshalling.

Features

  • Publish-subscribe pattern with type-safe event args
  • Automatic UI thread marshalling — subscribers registered on the UI thread receive callbacks on the UI thread, no manual dispatching needed
  • Filtered subscriptions — subscribe with a predicate to receive only matching events
  • Keyed events — route multiple event variants of the same type to different handlers
  • Dual dispatch modes — synchronous (Invoke) for ordered signals, async via thread pool (InvokeOnThreadPool) for fire-and-forget
  • Resilient — one subscriber throwing does not affect others; errors are routed to an OnError handler
  • Zero external dependencies

Installation

dotnet add package Raisin.EventSystem

Quick start

Basic publish and subscribe

var events = new EventSystem();

// Subscribe
events.Subscribe(mySubscriber); // implements IEventSubscriber<MessageArgs>

// Publish
events.Message(this, "Something happened", MessageSeverity.Info, "Category");

Implementing a subscriber

public class MyService : IEventSubscriber<MessageArgs>
{
    public void ExecuteEvent(object sender, MessageArgs e)
    {
        Console.WriteLine($"[{e.Severity}] {e.Message}");
    }

    public void DestroySubscriber() { /* cleanup */ }
}

Bulk subscription

// Registers all IEventSubscriber<T> interfaces on the object
events.SubscribeAll(myService);

// Unregisters all at once
events.DestroyAll(myService);

Filtered subscription

events.Subscribe(mySubscriber, filter: e => e.Severity >= MessageSeverity.Warning);

Built-in event types

Type Fields Purpose
MessageArgs Message, Severity, Category, Subcategory General application messages
LogArgs Message, Severity, Category, Subcategory File/diagnostic logging
AlertArgs Type, Message, Symbol, Category System and domain alerts

Severity levels: Detail, Verbose, Info, Warning, Error, Critical
