The tables from all of the databases are stored on the TFS 2012 server. Unable or cannot make changes to a table from one install of Toad and pull those changes on a separate / another install of Toad, just like how a version control system should work.
Also, add or remove a column from one of the tables, then commit that change to TFS, and then pull those changes on another install of Toad using the "Get latest revision" button, Toad generates a script that creates the new table, but does not populate it with the data. So the table has the correct columns, but all of the rows of data are erased.
WORKAROUND:
None
STATUS:
Waiting for fix in a future release of Toad for SQL Server.
