I had a bang-head-against-the-wall experience yesterday when I couldn’t figure out how to connect VS 2005 with my current VSS 6 database.  It kept wanting a web service interface (VSS 8.0).  I was about to log a bug on the VS 2005 Feedback Center when I browsed VS options to the source control node and found a combo box with available source control.  I changed the selection to regular VSS, and my problem was solved!  This may help someone else, so I thought I’d get it on the Net to Google can cache it.  I also posted this to the Whidbey private newsgroup.
