title: Entity Framework Include fails to compile
body: <p>I generated my entities via the <code>DbContext</code> generator, and added it to an API controller that uses my entities context model. The following method fails to compile though:</p>
  
  <pre><code>public IEnumerable&lt;casino&gt; Getcasinos()
      {
          var casinos = db.casinos.Include(c =&gt; c.city).Include(c =&gt; c.state);
          return casinos.AsEnumerable();
      }
  </code></pre>
  
  <p>The compiler says:</p>
  
  <pre><code>Cannot Convert Lambda Expression to Type 'String' Because It Is Not A Delegate Type
  </code></pre>
  
  <p>Any ideas why it is saying this? I have the <code>System.Linq</code> namespace imported.</p>
