I have installed VS2010 Express and C# Express Edition and MoQ.
I would like to know how can I execute the MoQ tests in class library without using the paid for version of VS2010?
I know NUnit has a UI, does MoQ have something similar, or is it just not possible?
In whatever project you wrote unit tests for NUnit, just add a reference to the Moq dll and you should be able to code the stubs/mocks there just fine. There is no UI for Moq. However, with the reference added to the unit test project, when you use the NUnit UI it will execute the code that uses Moq.
