For anyone who would like to try NCrunch with the VS2011 Developer Preview, know that you can simply copy the NCrunch extension directly into your VS2011 installation and it should work almost as normal.
i.e. just copy the files from:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Remco Software\NCrunch for Visual Studio 2010
into:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Remco Software\NCrunch for Visual Studio 2010
So far it seems the only thing that doesn't work right is the popup test list on the coverage markers. Everything looks to be ok.
I'll see what I can do about rigging up a proper installer etc ... meanwhile, if anyone finds any NCrunch regressions in VS2011, please post them here!
