title: Convert Sql query with Group by and Having clause to Linq To Sql query in C#
body: <p>I need help to convert following ql query to Linq to Sql query.</p>
  
  <pre><code>select Name, Address
  from Entity
  group by Name, Address
  having count(distinct LinkedTo) = 1
  </code></pre>
  
  <p>Idea is to find all unique Name, Address pairs who only have 1 distinct LinkedTo value. Remember that there are other columns in the table as well.</p>
