SharpDx工具包（DirectX）游戏中的黑屏

Question

I'm writing a SharpDx(directX) Windows Phone 8 game where everything worked until now. When I changed the size of the DrawingSurface, the phone screen during debugging was only black. Immediately I have everything undone and uninstalled the app, then the screen was still black. Now I have checked with breakpoints where the program stops working, at the end came out that, the phone every line passes through to the line

TouchCollection touchCollection = TouchPanel.GetState(); .

After that nothing happens, there is also no warning or anything. However, when I start the app without debugging, I can easily operate the app.

Has anyone an idea?

I have now found the solution to my problem.

Solution(Very simple):

The DrawingSurface doesn't work because an Microsoft Advertising SDK has disturbed it.
