Windows 7 - WPF - Framework 3.5 - Content does not appear in the developer or at startup

Question

Reference.

I seem to have broken WPF 3.5 in my development box. If I lay out VS2008 and create a new, empty WPF application, it does not display a constructor. If fact, I can see the desktop wallpaper through VS 2008. If I run the application, I get a window with the same pass-through properties. Plus, if I drag the application window, it leaves textures all over the screen.

If I create a new WPF 4.0 application in VS 2010 - no problem. If I target the app to 3.5, the designer is not crazy, but I get the same run-time problem as with VS 2008.

Please, help!

I do not know the exact cause of this problem, but I would consider the trial version and type of error:

1) Did Visual Studio work before? 2) Have you recently changed something, after which VS stopped working? 3) Are your video drivers updated? 4) Have you tried reselling VS settings (tools → import and export options → reset all settings)? 5) Have you tried reinstalling VS? 6) If you run another WPF application (not launched from VS), it will also disappear, will it leave artifacts? 7) Try to restore the system in the previous time where VS worked. 8) If everything else fails to reinstall Windows ... 9) If the problem persists after reinstalling, it is possible your hardware (for example, a graphics card) ...
