title: How can I exclude a specific file from TFS source control
body: <p>We have multiple config files (app.DEV.config, app.TEST.config, etc) and a pre-build event that copies the correct config file to app.config.  Obviously the configuration specific files are in source control --- but at the moment so is App.Config, and that shouldn't be.</p>
  
  <p>How can I mark that one file as excluded from source control, but obviously not from the project.</p>
  
  <p>I'm using VS 2005, and 2005 Team Explorer.</p>
