title: TFS WIQL does not support 'Does Not Contain'. Is there an alternative?
body: <p>Here is something that I can do from Visual Studio, but cannot seem to do through the TFS API using WIQL.</p>
  
  <pre><code>SELECT * 
  FROM WorkItems
  WHERE WorkItemType = Bug
  AND Tags CONTAINS 'MyTag'
  AND Tags DOES NOT CONTAIN 'OtherTag'
  </code></pre>
  
  <p>How do I query with a 'DOES NOT CONTAIN' filter?</p>
