After that, please follow some common steps to reinstall templates:

1) Please open Windows Explorer, and navigate to \Common7\IDE (by default is C:\Program Files \Microsoft Visual Studio 10.0\Common7\IDE);
2) Delete the ItemTemplatesCache, ProjectTemplatesCache folder; (If you are using VWDExpress, please delete folder under \Common7\IDE\VWDExpress)

我遇到这个问题，新建工程，或者打开以前的工程，一按回车键，就出这个错误
上面的方法不能用，或者嫌麻烦，就是用vs2010的安装程序的修复功能，修复一下就可以了
