It was installed correctly but not shown in my programs. then i uninstall it and re install VS11 Now The error comes when i Open my Project the designer view doesn't show the GUI. and shows my below errors.

We had this problem in Visual Studio 2010, too. This error suddenly disappeared as we switched to Visual Studio 2012 RC.

This could be a help to get your work done. So try to install it again. But I'm really interested to have an official statement from Microsoft, saying this bug is fixed in VS2012.
