title: Override mime type with VS Web Dev Server
body: <p>I would like to serve xbaps from the VS web dev server (cassini) to Firefox, but when served from the dev server, Firefox offers to download this file. As far as I can tell, this is because the dev server is serving the xbap file with a mime type of "application/octet-stream" instead of "application/x-ms-xbap", which works when served from IIS.</p>
  
  <p>Does anyone know how to change the mime type which the dev server uses for *.xbap files?</p>
