title: Creating a Patch with TFS
body: <p>Creating a patch is very easy in SubVersion, With Tortoise, you right-click and select Create Patch. But for the life of me, I can't find this functionality in TFS. Is this possible?</p>
  
  <p>If not, what's the standard way to submit patches in open source TFS hosted projects (a la CodePlex)?</p>
