Adding the additional project reference via Nuget with the corresponding 'using' and 'typeof' statement resolved the issue is the Test project for me as well.
In my real project I'm using several commercial modules which all have this problem. How can I tell which additional references need to be made to get those to work? The error message does not indicate which dependancy is missing, I haven't seen helpful information in any logs and I have not been able to find any other clues.
Thanks Broctune
