• 大部分时间重新启动Visual Studio 2015将修复此问题，但有时我必须通过从C：\Users {UserName} \AppData\Local\Microsoft\VisualStudio\14.0中删除所有项来手动清除组件缓存。 \ComponentModelCache




• 我以管理员身份运行VS2015。

解决方案

你应该去

 ％APPDATA％\Local\Microsoft\Visual Studio\< version> 
  

并删除ComponentModelChache目录。

Almost every time I try to run the update-database command for EF migrations, I get the following error in Visual Studio 2015:

• Most of the time restarting Visual Studio 2015 will fix this, but sometimes I have to clear the component cache manually by removing all items from C:\Users{UserName}\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

• I do run VS2015 as administrator.

解决方案

You should go to

%APPDATA%\Local\Microsoft\Visual Studio\<version>

and delete the ComponentModelChache directory.
