Visual Studio Component Cache Out of Date

Question

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

Exception calling "GetService" with "1" argument(s): "Exception calling "Invoke" with "2" argument(s): "The Visual Studio component cache is out of date. Please restart Visual Studio.

• 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.

Answer 1

You should go to

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

and delete the ComponentModelChache directory.
