title: How to write a "Between" Query Expression for today's date and two date attributes on an entity in a single condition?
body: <p>I have a "new_Term" entity with a "new_StartDate" and "new_EndDate" attributes.  I effectively want to write this statement in a single Query Expression:</p>
  
  <pre><code>new_StartDate &lt;= DateTime.UtcNow &lt;= new_EndDate
  </code></pre>
  
  <p>My first idea would be to use the Between ConditionOperator, but the between operator only works on a single attribute, ie:</p>
  
  <pre><code>// Not valid because the first parameter expects a string attribute name, not a value
  new ConditionExpression(DateTime.UtcNow.Date, ConditionOperator.Between, "new_startdate", "new_enddate")
  </code></pre>
  
  <p>Besides the obvious two Condition Expressions, is there a way to do it in a single Condition Expression?</p>
  
  <pre><code>new ConditionExpression("new_startdate", ConditionOperator.LessEqual, DateTime.UtcNow);
  new ConditionExpression("new_enddate", ConditionOperator.GreaterEqual, DateTime.UtcNow);
  </code></pre>
