title: Convert linq expression from method syntax to query syntax
body: <p>Well I've got a query</p>
  
  <pre><code>var grouped = from a in query
                group a.Payment by a.PaymentRecieverId
                into g
                select g;
  </code></pre>
  
  <p><code>query</code> is a <code>IQueryable</code> of <code>new { Payment payment, int PaymentRecieverId }</code></p>
  
  <p>How can I convert this method expression to query?</p>
