Since installing and starting to use StrongInject I get the following error showing up at the top of the IDE:

Thanks for reporting this. Have you tried reporting this to Roslyn? They will have more knowledge on how to diagnose this.

Closing as a roslyn issue. I believe this is fixed in more recent versions of roslyn.
