title: Entity to WCF datacontract
body: <p>I am using Enity Framework to fetch data from my database. In WCF, my method has a return type of <code>List&lt;EmployeeTable&gt;</code>. But I can't test my service in WCF test client.</p>
  
  <p>Do I need to write my custom datacontract to return the fetched data.</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>How can I handle this case:</p>
  
  <pre><code>var query = from c in customers
              join o in orders on c.ID equals o.ID
              select new { c.Name, o.Product };
  </code></pre>
