title: Change TFS collection of a Solution in Visual Studio 2010
body: <p>I am trying to setup TFS server for our Projects. I sucessfully setup and added one of the solution for testing to TFS source controls. But naming were test purposes only so i need to change it. I deleted TFS collections from administration panel and created a new one, but when try to add my solution to new collection it tries to connect old collection and -naturally- cannot find it, and raises error. I do not have same problem for other solutions but only for the solution i tested in the first time. </p>
  
  <p>things I've tried.</p>
  
  <ul>
  <li>file --> Source Control --> Change Source Control</li>
  <li>Deleting all source control files in solution folder</li>
  <li>Checked .sln file for references to old collection</li>
  <li>Restart the computer.</li>
  </ul>

  <p>edit:<br>
  Ok I have find solution to my problem. 
  The thing is Workspace info remained somewhere, I created a TPC and TP same name with the old ones. Then I manually removed Workspace info and then it worked. </p>
