To link to TFS 2012 or Visual Studio Online, update to the latest version of SQL Source Control.

If you don't want to update SQL Source Control, you need to edit a config file.

Editing the config file

1. Make sure SQL Server Management Studio is closed.
2. Go to the SQL Source Control config files folder. By default, this is located at %localappdata%\Red Gate\SQL Source Control 3

3. Open RedGate_SQLSourceControl_Engine_EngineOptions.xml in a text editor.

4. Below the EngineOptions version line, add:

   <TeamFoundationServerDllOverride>Tfs2012</TeamFoundationServerDllOverride>

   Ignoring any comments (indicated with <!->), the final file should look like this:

   RedGate_SQLSourceControl_Engine_EngineOptions.xml

   <EngineOptions version="3" type="EngineOptions">
   	<TeamFoundationServerDllOverride>Tfs2012</TeamFoundationServerDllOverride>
   </EngineOptions>

   The file is case sensitive. Don't change the capitalization of the text.

   The example above doesn't include any extra lines you may have included. For example, you may have included additional lines to set up change logging.

5. Save and close the file.
   

You can now link databases to TFS 2012 and Visual Studio Online.
