You may notice that when you attempt to add your solution to a source control in Visual Studio 2010, that it only shows a TFS server as a choice. Don’t be alarmed, however, just:
1. Go to Tools > Options.
2. Click Show all settings if not checked, then go to Source Control.
3. Go to Plug-in Selection, then change the dropdown to Microsoft Visual SourceSafe.
4. That’s it!
