title: LINQ Orderby Descending Query
body: <p>I have a LINQ query that I want to order by the most recently created date.</p>
  <p>I tried:</p>
  <pre><code>var itemList = from t in ctn.Items
                      where !t.Items &amp;&amp; t.DeliverySelection
                      orderby t.Delivery.SubmissionDate descending
                      select t;
  </code></pre>
  <p>I have also tried:</p>
  <pre><code>var itemList = (from t in ctn.Items
                       where !t.Items &amp;&amp; t.DeliverySelection
                       select t).OrderByDescending();
  </code></pre>
  <p>but this gives an error :</p>
  <pre class="lang-none prettyprint-override"><code>No overload for method 'OrderByDescending' takes 0 arguments
  </code></pre>
  <p>From what I've read, the first way it should work. I've tried changing <code>descending</code> to <code>ascending</code> just to see if it does anything but it stays the same.</p>
  <p>What am I doing wrong?</p>
