Reading about performance improvements gained by using a RAM-drive, I went ahead and set one up.
I made the mistake of typing the path for "Workspace base path" as "M:/NCrunch", rather than "M:\NCrunch". The problem is that things seem to work until you notice, too late in my case, that the coverage markers have gone away. Looks like the build part of NCrunch is tolerant of unixy paths, while the coverage marker bits are not.
Easy fix - put a file browser/validator in the configuration GUI rather than a raw text field.
I found the benefit of the RAM disk quite dramatic - maybe it would be worthwhile bundling one into NCrunch or making the idea of installing one even more obvious to a first time user? NCrunch is the perfect application for RAM disks - I have also found them very helpful in integration tests which require disk files.
Great tool BTW!
Cheers, George.
