title: Get media elements from RSS using SyndicationFeed
body: <p>I'm attempting to parse an RSS feed using C# and the SyndicationFeed class. I'm iterating over the items to get a list of SyndicationItems and that is exposing most of the feed properties, but what I cannot get out is the media:thumbnail element:</p>

  <p>The entire media:content block is not deserialized from the XML passed in.
  I've iterated over the entire element extensions block using</p>
  
  <pre><code>foreach (SyndicationElementExtension extension in item.ElementExtensions)
  </code></pre>
  
  <p>but its not in there.
  Is there any way I can tell the SyndicationFeed.Load() method to also parse this block for me:</p>
  
  <pre><code>SyndicationFeed feed = SyndicationFeed.Load(xmlReader);
  </code></pre>
