Do you know any good unit testing and mocking frameworks for C#?

[JamesRichmond]

I'm searching for a good unit testing and mocking framework for C# (not necessarily open source). Any suggestions?

[jschell]

I used to use nunit. Used to only because I haven't done any C# for a while. As long as it is being maintained I presume it is very usable. I didn't use mocks then but googling certainly suggest that they exist.

For mocking, I love JustMock from Telerik. It allows you to mock things that other mocking frameworks just can't cope with.

I usually use NUnit for test running, though we are thinking about porting to XUnit. For mocking we use Typemock as we need to deal with some legacy code. You can use Moq as well if you're starting a new project or if your code is testable. I've used it before when we were employing TDD from the beginning.

Moq is also good.
