title: How do I return an entity that is a query of multiple tables
body: <p>I have a web service that uses the Entity Framework for storage and exposes a public API for CRUD operations.</p>
  
  <p>If I have an entity such as User which has a 1 to many relationship with a Car entity, how do I easily return in my web service method of GetUser(int userId) a instance of user that looks like this:</p>
  
  <pre><code>public class User{
    string Id;
    IEnumberable&lt;Car&gt; Cars;
  }
  </code></pre>
  
  <p>Does this work by default within the entity framework, because I assume that the Cars property is lazy when using it on the server side.</p>
