How do I remove dependency on Command and Xamarin.Forms in View-Model when following MVVM pattern?

Hi,

I have read tons about following the MVVM pattern in Xamarin.Forms. To follow pure MVVM, there seem to be two main problems: (1) how to perform navigation without depending on Navigation (and the dependency on Xamarin.Forms in the View-Model classes); and (2) how to use commands without using the Command type (and again depending on Xamarin.Forms).

I have read lots of solutions for the first problem, but I don't seem to be able to find anything on solving the second problem. It seems to me that I need to implement my own concrete type implementing the ICommand interface, but I can't find any good information on how to do this.

Can anyone point me at some good information on how to do this, or tell me if I am barking up completely the wrong tree?

Kind wishes ~ Patrick
