Let go of my assembly!
As noted earlier, I'm using FxCop for the first time today. So I've got FxCop up with it's results, I'm doing ALT-TAB back and forth to clean up some of the easier things. Now I want to re-build and re-analyze but FxCop has my assembly locked. No biggie, I'll start up a new FxCop project and re-build. Still locked. I had to shut down FxCop before I could rebuild.
I've gotten spoiled by using the nUnit GUI so much recently. It doesn't lock my test fixture assemblies and allows me to rebuild them without shutting down the GUI.
