title: Linq to SQL: how to aggregate without a group by?
body: <p>I am searching for the Linq-to-SQL equivalent to this query:</p>
  
  <pre><code>SELECT
    [cnt]=COUNT(*),
    [colB]=SUM(colB),
    [colC]=SUM(colC),
    [colD]=SUM(colD)
  FROM myTable
  </code></pre>
  
  <p>This is <strong>an aggregate without a group by</strong>. I can't seem to find any way to do this, short of issuing four separate queries (one Count and three Sum). Any ideas?</p>
