There are many times when I need to test a little snippet of .net code but rebuilding and publishing the entire project or writing a suite of unit tests just seems like overkill. For example, I am writing a regular expression right now and I want to see if it the pattern is matching on the right parts. I could go and find a million other utilities that do that sort of thing, but that is not exactly my point.

FireBug has an exact analogue to what I want - the FireBug console. There is a text box where the user can enter some JavaScript and FireBug will execute it on the spot and display the return value.

I would love to be able to enter something like (new Regex("b+")).Replace("abc", "x") and see the results without having to do all the overhead. Does VS have anything like this?
