title: LINQ to Entity Framwork: return sorted list of related rows
body: <p>Table Category (c) has a 1:many relationship with Table Question:   a Category can have many Questions but a Question belongs only to one category.  The questions are also ranked in terms of difficulty.  </p>
  
  <p>I would like a LINQ to EF query that would return all Categories with related Questions but the Questions should be sorted ascending in terms of difficulty (lets say on the Question.Rank column).</p>
  
  <p>My query so far, is missing the sorted of the questions:</p>
  
  <pre><code>var results = from c in context.Category.Include("Question") select c; 
  </code></pre>
  
  <p>How needs to be added to get the questions sorted?</p>
