Can someone explain how the mediator pattern works with multiple instances.
My code in the view:
public MyView() {
Mediator.Register("CloseWindow",()=>Close());
}
and in the ViewModel:
public SomeMethod() {
Mediator.Notify("CloseWindow");
}
This works find as long as there is only one instance of the View - ViewModel pair.
How do I solve it with multiple instances?
I use an alternative solution. MyView implements an interface IMyView which contains the Close method. The MyViewModel object associates the View and so it can call the Close method through the interface.
