title: Using SetFields with MongoDB C# driver 2.0
body: <p>With the old driver I could specify the fields I wanted to return from a query as follows:</p>
  
  <pre><code>var cursor = Collection.Find(query).
    SetFields(Fields&lt;MealPlan&gt;.Exclude (plan =&gt; plan.Meals));
  </code></pre>
  
  <p>How do I accomplish this with the 2.0 driver?</p>
