I’m trying VSNUnit at the moment – it’s an open source Visual Studio plugin that puts the NUnit interface into VS 2003/05.
I’ve tried it on one test at the moment and it seems to work fine.
Edit: This is the second app that I've run today that hasnt lasted 5 mins. I was having a strange problem with it only running once before, then not. I read the project forums and apparenty the project has been abandoned as there is another tool out there that is better. oh well...
So im going to give this new one a try - Testrunner. hopefully this one is better, although it looks like you have to pay for commercial use.
