>Maybe this is a sanity-check question...for those (Bonnie and anyone else) who have taken the time to decouple as much as possible...do you all wind up with quite a large # of references/dependencies in your solution?

Kevin,

I don't know what you call 'alot'. Generally we have our Base Framework .dll that is referenced by all projects.

We have our data tier, which references the Framework Base. The business tier, which of course references the data tier. The UI tier, references the business tier.

Never should the UI talk to the data tier, so you should need to reference the data tier in the UI tier.

The bottom line is though, that in the final UI projects bin, you are going to end up with ALL the DLL's in your solution (unless you have GAC installed DLLs.)

Althought, as you said, VS.Net is still a little buggy and tells you it can't create or copy a DLL cause it is in use, and VS.Net it self is the one that has it in use. Hopefully the will fix this in Widbey.
