Controllers in MVVM, How to get info from viewmodel to it's controller?

Question

We are building an app using the MVVM pattern, we have controllers that wire up all the views and viewmodels using DI. All examples of MVVM I\'ve seen are really simplistic

Answer 1

How about using events wherein the controller subscribes to VM events or using a mediator pattern where in a mediator is injected in a VM.
