I have Visual Studio 2012 + Resharper 7.1.1000.900 + StyleCop 4.7.44 installed.
The problem is that no shortcuts
For me the issue was in Resharper License. It has been delinked from my account for some reason and it said that the license is invalid. When I linked it again to my JetBrains account it started to work properly after a few minutes.
