Hi, thanks for offering to help. If you follow the documentation on how to build the solution that'll get you up and running. Once you have the source take a look at the folder C:\Dev\StyleCop-main\Project\VisualStudioTemplates\ItemTemplates\CSharp\Code\1033
These are the templates for VS2010 Class CodeFile and Interface.
Once you've created the templates that are StyleCop compliant the next piece of work is on the installer. If you know WiX then that'll be fine. If not you can always submit a fork with all the templates you've created for VS2012 and I will update the installer.
