要在 VS2013 ultimate 中解决这个问题，我必须关注帖子 http://rathodkrunal.blogspot.com/2011/11/visual-studio-2010-error-hresult-efail.html

其中讨论了简单地清除 Visual Studio 的 ItemTemplateCache 并使用/setup 标志运行 vs 一次。

如果链接断开或不可用，这里是旧 VS 的缓存所在的位置:

You can delete the project cache at "Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache", then run "devenv /setup" to build the cache again to see if it helps.
