I have a game built on the XNA 4.0 studio and was wondering if it is possible to convert it to a WPF (Windows Presentation Foundation) to work on a microsoft tablet. I tried to duplicate all the code in visual c# 2010 (from xna file to surface xna) but it just sits on a black screen and freezes. The one difference i notice is that there is a app1.cs file instead of game1.cs (I just renamed the previous game1 calls to app1). I did not touch the xml file but I am assuming i have to include the xml to show the game. Is this even possible?
