title: How do I use SyndicationFeed?
body: <p>This may seem like a dumb question, but I cannot for the life of me figure out how to get access to the <code>SyndicationFeed</code> class in c#. Every single example I have seen on MSDN or otherwise assumes that it's already imported, and not a single one I have found gives any indication on where it's located.</p>
  
  <p>For example, I'm trying to run the following:</p>
  
  <pre><code>XmlReader reader = XmlReader.Create(rss_url);
  SyndicationFeed.Load(reader);
  </code></pre>
  
  <p>But it fails because <code>SyndicationFeed</code> doesn't exist in the current context. Does anybody out there know how I can get it in?</p>
