title: Using DateTime.Add(TimeSpan) with LINQ
body: <p>I have to run a query like the one bellow. It is actually more complex, but here is the part that matters:</p>
  
  <pre><code>var results =
      from b in _context.Bookings
      where b.ScheduleDate.Add(b.StartTime) &gt;= DateTime.UtcNow
      select b;
  </code></pre>
  
  <p>But it gives the following error:</p>
  
  <blockquote>
    <p>LINQ to Entities does not recognize the method 'System.DateTime.Add
    method(System.TimeSpan)', and this method cannot be translated into a
    store expression.</p>
  </blockquote>
  
  <p>How can I work around this?</p>
  
  <p>Thanks in advance.</p>
