WeakEventAggregator

The WeakEventAggregatoris an easy to use EventAggregator providing following benefits

• Factory to create a named EventAggregator instance
• Subscribe events
• Publish events

EvantArgs (Payloads) are all classes that implements the (empty) IPayload interface

Release Notes

Example

Creating an instance

var eventAggregator = Factory.GetNewEventAggregatorInstance("myEvAgg", false);

Using the following delegate/method

private static void ShowMessage(MsgEventArgs eventArgs)
{
    MessageBox.Show(eventArgs.Message, eventArgs.Title);
}

Subscribing an event 'MsgEvent' and event args (payload) of type MsgEventArgs

eventAggregator.Subscribe<MsgEvent, MsgEventArgs>(ShowMessage);

Raising an event

eventAggregator.Publish<MsgEvent, MsgEventArgs>(new MsgEventArgs { Message = "Test" });

Unsubscribing an event 'MsgEvent'

eventAggregator.Unsubscribe<MsgEvent, MsgEventArgs>(ShowMessage);

This example uses this event

public class MsgEvent : IEvent
{
}

and this event args (payload)

public class MsgEventArgs : IPayload
{
    public string Title { get; set; } = string.Empty;
    public string Message { get; set; } = string.Empty;
}
