title: Add Include to existing object in entity framework
body: <p>I've created an object in entity framework and want to include some related classes after the fact.  How can I do this or what keywords should I be searching for?</p>
  
  <pre><code>Order myOrder = 
  
  context.Orders
          .Include("Category")
          .Include("Customer");
  
  // Some logic here
  
  
  myOrder = myOrder.Include("Supplier");
  </code></pre>
