title: Field not showing in TFS 2017 WebLayout
body: <p>I have enabled the new work item form in TFS 2017 after upgrading from TFS 2015, but have found that there are some fields that aren't showing in the new work item form, even though I can see the field declared in the WebLayout section when editing the work item type XML. Is there a condition which hides fields in WebLayout?</p>
  
  <p>The field I am trying to get appear is the <code>Microsoft.VSTS.Scheduling.RemainingWork</code> field. I have the following inside the WebLayout:</p>
  
  <pre><code>&lt;WebLayout&gt;
      &lt;!- Snipped some other groups which show --&gt;
      &lt;Group Label="Timescales"&gt;
         &lt;!-- Snipped Some other fields which show --&gt;
         &lt;Control FieldName="Microsoft.VSTS.Scheduling.RemainingWork" Type="FieldControl" Label="Remaining Work" /&gt;
      &lt;/Group&gt;
  &lt;/WebLayout&gt;
  </code></pre>
  
  <p>I also had the same issue with a custom String field, but I no longer needed the field so I removed it anyway.</p>
