Seems i'm a little slow on this but ReSharper 2.0 has gone gold. I've been using it since the early beta and must say i'm impressed. The main plus to me is finally getting the 'green bar' in VS.NET (TestDriven.net displays test results as text).
I'm not sure why but there's definitely some psychological benefit of seeing the green/red bar when running unit tests!
As well as unit testing support, this new version adds a few new refactorings, editor support for Nant, MSBuild and ASP.NET files.
