Unfortunately Resharper has a long history of breaking MBUnit support with every new release. I noticed version 6.1 has been released, but I can't use it until it works properly with MBUnit.
So, does Resharper still work with MBUnit? I'd try it myself, but last time I did I lost all of my Resharper settings while downgrading, so I thought I'd better ask first this time.
Thanks,
Adrian
There's no official Gallio release supporting ReSharper 6.1 just yet. However, 6.1 support is a work in progress and latest development builds were known to work with 6.1 EAP - no guarantees yet though.
