Version 1.0 of xUnit.net has been released. So do we need another unit test framework? And I think the answer is yes. There are a number of things that I've found a little bit weird in NUnit and with xUnit.net they have been removed. I definitely think that you should take a closer look at why xUnit.net was written and the comparison with other unit test frameworks. xUnit.net definitely feels like a new fresh wind in the TDD/BDD toolbox.
