It seems that your solution is not connected to the Team Foundation Server.
I would recommened that you remove the mapping of your workspace, delete all local files of the workspace and then get a fresh version (Get latest version) from the Team Foundation Server.
To remove mapping you need to open the Source Control Explorer in Visual Studio. Navigate to the Branch you are working on and open the Context Menu (right click on branch). In the menu you select Advanced->Remove mappings....

What you also can do is to check the state of your workspace/solution if it is connected to TFS. To do that you need to open the solution in Visual Studio and then open File->SourceControl->Advanced->Change Source Control... in the File Menu of Visual Studio.
