We have just released a new StyleCop BETA which is identical to the previous release except that it adds the ability to integrate into the Visual Studio 2010 shell. After installing this release, you should see the familiar StyleCop menus showing up in both VS 2010 and VS 2008.
We plan to leave this release in BETA for a couple of weeks. If you decide to try it out, will you please let us know whether it’s working as expected for you?
