Sounds like Rick does, but I would not do it that way. I'd treat is seperately and just reference the DLL. If you get an error from the framework, it indicates you need an additional test case on it, so you should add that to your unit tests for the framework, fix the bug, and recompile the framework.
>Yes, but should we include the framework project in all projects?
