title: Entity Framework - get related entities from List<T>
body: <p>I'm using EF4.3 with DbContext.</p>
  
  <p>I have entities that I store in cookies.</p>
  
  <p>When a user returns to the site, I currently parse the cookie values to List, however, the entity "BookmarkedDeals" has a navigation property of "Deal" and I would like to make the list IQueryable so I can simply attach the navigation property either eager or lazy loading</p>
  
  <p>Having got a list, this is what I initially tried;</p>
  
  <pre><code>List&lt;BookmarkedDeals&gt; bd = // populate it from cookie
  
  var query = bd.AsQueryable().Include("Deal");
  </code></pre>
  
  <p>However Deal is null.</p>
  
  <p>Anyone know how this can be achieved?</p>
