How to pass the UI Dispatcher to the ViewModel

Question

I\'m supposed to be able to access the Dispatcher that belongs to the View I need to pass it to the ViewModel. But the View should not know anything about the ViewModel, so

Answer 1

I get the ViewModel to store the current dispatcher as a member.

If the ViewModel is created by the view, you know that the current dispatcher at creation time will be the View's dispatcher.

class MyViewModel
{
    readonly Dispatcher _dispatcher;
    public MyViewModel()
    {
        _dispatcher = Dispatcher.CurrentDispatcher;
    }
}
