  <p>option as I was intending it to be a throwaway project. However, I now want to keep it so I am trying to add it to source control after the fact.</p>
  
  <p>I've tried both adding the project to source control when the project is open and moving the files from the "Excluded Changes" section of the Pending Changes window. In both cases I get the following error:</p>
  
  <blockquote>
    <p>TF10169: Unsupported pending change attempted on team project folder $/RadioButtonTest.  Use the Project Creation Wizard in Team Explorer to create a project or the Team Project deletion tool to delete one.</p>
  </blockquote>
  
  <p>My default collection is mapped to E:\Chris\projects and the project I'm trying to add is directly in that folder.</p>
  
  <p>What am I missing?</p>
