Same as yanglee. It doesn't bother me either way. I've usually got a whole host of things to add to the ignore files for any new project anyway that a couple more for NCrunch won't make any odds. But if you do decide to do it, then that's a little bit of work I don't need to worry about in future. Having said that, there are other things that would probably take priority in my world view. A TeamCity(+Hudson+Jenkins+CC) plugin and server runner for the code coverage stats for instance.
