Visual Studio Crash After Installing Windows Phone 7 SDK

After installing Windows Phone 7 SDK, when you start Visual Studio 2010 and Click on New Project or immediately after starting Visual Studio 2010, Visual Studio crash run following command in Visual Studio Command Prompt by going to Start > All Programs > Visual Studio 2010 > Visual Studio Tools > Visual Studio Command Prompt

devenv.exe /installvstemplates

Cause: if you run devenv.exe /Log C:\output.txt in your txt file you will notice that there are some duplicate entries for the Project Templates. By running above specified command it will reinstall VS Templates, and solve the issue.

Happy Windows Phone 7 Development :)
