Overview

In-process pub/sub decoupling publishers from subscribers. No source generator — pure runtime API.

IEventHandler<TEvent> — typed handler
Default implementation: thread-safe in-memory aggregator

csharp

var aggregator = new EventAggregator();
aggregator.Subscribe<OrderPlaced>(new EmailHandler());
aggregator.Publish(new OrderPlaced(orderId, total));
