title: Silverlight file download for COM Interop
body: <p>Is the following possible in Silverlight when a button is clicked?</p>
  
  <ul>
  <li>An Excel template is downloaded from
  a remote server and saved to the local machine </li>
  <li>An instance of the
  template is then opened on the client</li>
  <li>A macro is then executed within the
  new Excel document</li>
  </ul>
  
  <p>I can do everything apart from saving the template to the local machine. I can save this in isolated storage but then I don’t know where this is when trying to open it from the Excel COM interop code. Has anyone any ideas or is this not possible?</p>
