❔ Trigger MediaElement.play() the MVVM way?

I have the mediaelement defined in the view, how would I cause a button click to trigger it?

Someone asked that exact question on SO: https://stackoverflow.com/questions/10631748/mvvm-pattern-violation-mediaelement-play

Basically the second answer of the StackOverflow question. You wrap the MediaElement in an Interface, create a new UserControl with them and then use the UserControl.
