Currently, you can only "link to a db already in source control" that was placed in source control by SQL Source Control. (This is for 5 users that each have their own dedicated db to link to the same centralized repository to share changes with each other. 1 user creates the link and the other 4 users "link to a db already in source control.") We have a specific format, so we currently can't link to existing "non-SQL Source Control" directories.
How did your database get into TFS initially? Were you using SQL Compare? Were you using the default file format? If so, there may be a workaround so that you can use your existing project and maintain all its history. Please contact firstname.lastname@example.org
if this is the case and you would like more information on linking to an existing SQL Compare repository.
If not, how did your db get into TFS? What process has your team been using?
We may consider integrating with VS 2010 DB Projects in a future version. Is this something that would interest you? This would allow users to work in SSMS or VS.
