How can I configure a .NET solution (C#, .NET 2.0) to to allow other developers to make use of the same unit tests for the solution using either NUnit or MSTest?
Do you have a mix of existing tests? If not, or you don't mind converting existing MSTests, I would standardize on NUnit. I strongly prefer NUnit over MSTest; it's faster and it doesn't force you to have the TestContext nonsense in your test classes. It's also more compatible with CI servers.
