title: How can I generate a diff from within Visual Studio for a codeplex project?
body: <p>I made some changes  in the sourcecode for a project hosted on codeplex.
  I'm not an author or editor on the project - just a user.
  But I'd like to submit the changes as a patch.</p>
  
  <p>Codeplex has a nice way to do upload the patch...</p>

  <p>How can I generate a patch or a diff, from within Visual Studio?  How can I generate something that another VS developer could apply to update his source code?  <strong>Does VS have a patch/diff capability?</strong></p>
  
  <p>Thanks.</p>
