title: how to access attributes of linked entity?
body: <p>I fetch all <code>Item</code> with their linked <code>Location</code>, and want to show the name of each item together with the name of its location:</p>
  
  <pre><code>var query = new QueryExpression("xxxxx_item");
  query.ColumnSet.AddColumns("xxxxx_name");
  var locationLink = query.AddLink("xxxxx_location", "xxxxx_location", "xxxxx_locationid", JoinOperator.LeftOuter)
  locationLink.ColumnSet.AddColumns("xxxxx_name");
  
  var result = crmService.RetrieveMultiple(query).Entities.Select(e =&gt; e.ToEntity&lt;xxxx_Item&gt;()).ToList();
  </code></pre>
  
  <p>How do I loop over the resulting List and show both <code>Item.Name</code> and the <code>Item.Location.Name</code> ?</p>
