title: Tfs missing a PDF mapping
body: <p>I am trying to add a MSI project to TFS. The system that the MSI file installs has a PDF manual, so this PDF manuel is part of the project. But when I try to add the project, I get following error:</p>
  
  <p>The item 'manal.pdf' cannot be added to source control because the item has no source control mapping.....</p>
  
  <p>Can I do something about this? Of course TFS cannot detect changes etc. I simply want to store it along with the other files.</p>
