MVVM and Windows Phone application bar

Working a cross platform mobile solution.  I have the Commands defined in my mvvm core View Model.  I need to bind my View in the Windows Phone 8 application to the command in the ViewModel. 

Problem:
"Windows Phone AppBar's are naive rather than Silverlight controls - so they are not bindable"

Solution:
Get an addon which will support app bar binding for windows phone 8.
