title: Cannot see go online option in tfs
body: <p>I opened a solution in offline mode. But now I am trying to go online and connect to tfs but I cannot seem to see the "Go Online" Button under File-> Source Control.</p>
  
  <p>I connected to TFS using Team-> Connect to Team Foundation Server option but I still don't see "Go Online" button in File-> Source Control. </p>
  
  <p>Is there any other way to go online in TFS?</p>
  
  <p>Version used : Visual Studio 2010 Ultimate, connecting Team Foundation Server 2010.</p>
