This project was abandoned for over a year before some new members were added, which is why so many forks were created.
I just released v4.7.52, which is probably your best bet. It works with all versions of Visual Studio from 2008 to 2015, and ReSharper from 5.1 to 10.0.2.
If you ever stop using VS2013 (and only use 2015 or newer), you might be interested in the
project, which is a re-implementation (with some changes) based on Roslyn.
