Feature: reference IMethod as a delegate in a template

[gfraiteur]

There is currently no way to reference an introduced method or an IMethod as a delegate i.e.

dictionary.OnDictionaryChanged += myDictionaryChangedMethod; //Doesn't like this since IMethod isn't a System.EventHandler

Ideally support for this feature will also be paired with a way to unsubscribe from the event (e.g. within a Dispose or DisposeAsync method) as well - thanks!

An interesting question is: to which delegate type?
It could default to a Func or Action but I guess that in some cases you may want to pass your own delegate type.

[WhitWaldo]

I think it'd need to be open to whatever it is that I pass it - my immediate need was to simply provide an Action for a third-party event, meaning I'd have little control over its shape. It could just as easily have required a Func instead.

Raising the priority of this ticket because it seems both forgotten, simple, and good value.
