>It does for me when I have connectivity issues or problem authenticating with the TFS server. If you have no connection when you first start VS, then you can elect to work offline. However if the connection goes down with the TFS Server after you have the solution open, it's a mess until you exit VS and come back in offline or with a good connection. It can seem to take forever to try the connection until it finally decides it cannot communicate with the TFS server. My TFS server is in another state and there seldom are issues, but when there are it's a major headache.

Tracy, I don't find that a problem (losing connectivity with TFS once VS is open) ... as long as I don't need to check anything in/out. I just don't see it as "a mess" as you say. It may depend on your source control settings though I suppose. I have mine set up to only check-out something when I Save a file, not when I edit it ... that way, I have better control over when I need to actually access TFS and won't do it if I know I'm not connected to TFS.
