title: References needed to use Open XML from within .net web application
body: <p>I'm about to give up with Word automation from within a .net application and am going to try using Open XML.</p>
  
  <p>It seems I need references to:</p>
  
  <pre><code>using System.IO;
  using System.IO.Packaging
  using DocumentFormat.OpenXm;l.Packaging;
  </code></pre>
  
  <p>After a bit of ferreting around I found you need to add a reference to Windows Base to get System.IO.Packaging to appear.</p>
  
  <p>What do you need to reference to get to use DocumentFormat.OpenXml.Packaging? I can't find it anywhere. I thought you might have to reference something like Microsoft.Office but that is not available either.</p>
