MPowerKit.Events

This library gives you an ability to facilitate communication between loosely coupled components in an application.

Inspired by Prism's EventAggregator.

Note: Main difference from Prism is that this library does not support different threads event publishing/handling. The event will be handled in that thread it was raised in. Also, code was refactored to use latest .net and c# features.

Usage

Register event aggregator in service collection:

serviceCollection.AddSingleton<IEventAggregator, EventAggregator>();

or use as singleton

EventAggregator.Current.GetEvent<>()

Create an event:

public class SomeEvent : PubSubEvent { }

or generic version

public class SomeGenericEvent : PubSubEvent<payload_type> { }

Subscribe to an event:

IEventAggregator _eventAggregator;

public void EventHandler() { }

_eventAggregator.GetEvent<SomeEvent>().Subscribe(EventHandler);

public void GenericEventHandler(payload_type payload) { }

_eventAggregator.GetEvent<SomeGenericEvent>().Subscribe(GenericEventHandler);

Publish an event:

IEventAggregator _eventAggregator;

_eventAggregator.GetEvent<SomeEvent>().Publish();

_eventAggregator.GetEvent<SomeGenericEvent>().Publish(payload);

Note: you may not unsubscribe from events, because it has weak reference, but better to do unsubscribe
