Visual Studio package that automatically fixes StyleCop warnings.
Once you have a list of the StyleCop warnings in the Visual Studio ErrorList window you are then able to right click and select Fix It. If the warning is in the list StyleCopFixer will fix it for you.
** Update **
Dropped the ball on this one a little as I have been using Resharper that I highly recommend. I am now in another role and we don't have Resharper :( so I'm going to get the bugs fixed and more rules incorporated.
