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

Maybe I am a bit late to this discussion, but I found 1 nice article https://msdn.microsoft.com/en-us/magazine/dn605875.aspx

There is 1 paragraph

Furthermore, all code outside the View layer (that is, the ViewModel and Model layers, services, and so on) should not depend on any type tied to a specific UI platform. Any direct use of Dispatcher (WPF/Xamarin/Windows Phone/Silverlight), CoreDispatcher (Windows Store), or ISynchronizeInvoke (Windows Forms) is a bad idea. (SynchronizationContext is marginally better, but barely.) For example, there’s a lot of code on the Internet that does some asynchronous work and then uses Dispatcher to update the UI; a more portable and less cumbersome solution is to use await for asynchronous work and update the UI without using Dispatcher.

Assume if you can use async/await properly, this is not an issue.
