I've got the latest mspec from the codebetter teamcity site and installed the Resharper5.1 runner as suggested. The runner and the annotations show up fine in the resharper option dialogs.
Now even with the annotations library ticked I still get "field xxx is never used" warnings everywhere and when I ask resharper to run all tests in the solution it doesn't seem to find my specifications.
I have unblocked the dlls.
Using resharper 5.1.
