title: deal with an importer XNA
body: <p>I added <code>test1.bin</code> to the content of my game. There is already a <code>test.bin</code> which works perfectly. The problem I have is :</p>
  
  <blockquote>
    <p>Erreur 11: Cannot autodetect which importer to use for
    "Levels\test1.bin". There are no importers which handle this file
    type. Specify the importer that handles this file type in your
    project.</p>
