Hi Paul,
After a quick smoke test, it looks as though NCrunch for VS2012 already works with VS2013. The installer won't work, but you should be able to perform a manual installation into the Visual Studio 12 directory.
I've updated the
manual installation instructions to include notes for a VS2013 installation.
A new installer will be introduced for VS2013 as part of the 1.46 maintenance release due out next month.
Microsoft definitely has a good handle on that backwards compatibility! :)
Cheers,
Remco
