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

for WPF and Windows store apps use:-

       System.Windows.Application.Current.Dispatcher.Invoke((Action)(() => {ObservableCollectionMemeberOfVM.Add("xx"); } ));

keeping reference to GUI dispatcher is not really the right way.

if that doesn't work (such as in case of windows phone 8 apps) then use:-

       Deployment.Current.Dispatcher
