Version 4.5.9.0 of Stylecop has been released at http://stylecop.codeplex.com/releases/view/62209
Whilst still a "beta" version, it is excellent.
- The installation file will install over a previous version.
- It comes with ReSharper Integration
- Problems with FileHeaderFileNameDocumentationMustMatchTypeName have been fixed.
I suggest you try this new version. I have found it to be excellent.
