It has been said that if you know Silverlight then you are already a Windows Phone 7 developer. Jesse Liberty joins John Papa this week to explore that statement and demonstrate the side-by-side creation of both a Silverlight application and a Windows Phone application.      Watch as Jesse cracks open Visual Studio 2010 and creates two similar applications: one for Silverlight and one for Windows Phone 7. He does this all from scratch so you get to see every step along the way.
