title: What is the difference between "Compare with Workspace version" and "Compare with Latest version"?
body: <p>I am using Visual Studio 2012 with TFS.
  Whenever I want to compare my checked out files, I have two options to choose from:</p>
  
  <ol>
  <li>Compare with workspace version</li>
  <li>Compare with latest version</li>
  </ol>
