Thanks for your post.

Which kind of project do you want to create? Does it a WPF template?

Your issue appears to be a template corrupt issue. To fix it, please follow some steps below:

1. Open your Control panel -> Programs -> Programs and Features, right click Microsoft Visual Studio 2010 -> Uninstall/Change -> repair/reinstall

2. Open Windows Explorer, and navigate to <Visual Studio Installation Path>\Common7\IDE (by default is C:\Program Files \Microsoft Visual Studio 10.0\Common7\IDE);

3. Delete the ItemTemplatesCache, ProjectTemplatesCache folder;

4. Open Visual Studio Command Prompt (2010) under Start menu -> All Programs -> Microsoft Visual Studio 2010 -> Visual Studio Tools (run it with Administrator privilege: right-click the program -> Run as administrator);

5. Run the devenv /InstallVSTemplates switch;

6. Run the devenv /Setup switch

If above steps cannot reset the templates, please refer to the following link:
