title: Cannot implicitly convert type Models to string issues
body: <p>I really dont know what went wrong: I was following tutorials on rest web services using asp.net web api and i got this error in <code>GET(int id)</code>: 
  cannot implicitly convert type <code>Models.Client</code> to <code>string</code></p>
  
  <p>here's my code:</p>
  
  <pre><code>public string Get(int id)
  {
      using (ClientDB db = new ClientDB())
      {
          return db.Clients.FirstOrDefault&lt;Client&gt;(c =&gt; c.Id == id);
      }
  }
  </code></pre>
  
  <p>Id from the model is type integer and so is <code>id</code>
  and i also tried <code>SingleOrDefault</code> instead of <code>FirstOrDefault</code></p>
