title: How to get an object from the HttpResponseMessage?
body: <p>I have a Post method that returns an <code>HttpResponseMessage</code>: </p>
  
  <pre><code>HttpResponseMessage response = 
      Request.CreateResponse(HttpStatusCode.Created, updatedItemDto);
  </code></pre>
  
  <p>I'm writing some tests for this and would like to get the updated item from the <code>HttpResponseMessage</code> (particularly the <code>ItemId</code>).  I tried inspecting the object and it looks like the object lives in <code>Response.Content</code>, but I don't know how to get it from the <code>Content</code>.  </p>
