I am trying to run some unit tests using NUnit while I have the project open, and VS 2010 cannot rebuild the project while the assembly is loaded in NUnit. I have looked around and haven't found any solutions that seen to fix it. I can close NUnit, then the project builds fine. This is a the same solution based on Rob Conery's BDD demo found here: http://tekpub.com/view/concepts/5
Any thoughts?
