I haven't posted any new builds of NUnitAddin for a while. The reason is because I've been working on a version that supports Rotor, Mono and multiple versions of the .NET Framework. It has been coming on well, but not quite ready for release. It is fun being able to test snippets of code with Mono from the safety of Visual Studio.NET. ;o) I must say I'm very impressed with the Mono runtime's startup speed (especially when compared to Rotor).
If anyone is eager to get going with NUnitAddin and Rotor/Mono - drop me a line and I'll send you an alpha version. Otherwise, watch this space.
