Hi,

I want to stub a Interface containing a event with a delegate which returns a Task.

delegate Task AsyncEventHandler(object sender, EventArgs eventArgs);
event AsyncEventHandler AsyncEvent;

If I now try to generate a stub, SimpleStubs handles this event like a normal event and creates a AsyncEvent_Raise method with return type void. But of corse this wont work if I want to await the raised event in my unit tests.

I created a extension method to raise such an async event in my code (see AsyncEventHandlerExtension in repo solution). There you can see what to do if an event delagate is having a Task as return type.

But maybe you just return an IEnumerable<T> to handle every return type and let it to the user to handle the return type.

Repo solution: SimpleStubsAndAsyncEvent.zip

Repo steps:

1. Restore nuget packages
2. Build solution
   => build error "can not await void" in TestClass.cs
