title: MongoDb - Data from Foreign Key Table in One Call
body: <p>Let's say I have two collections in MongoDb: </p>
  
  <ol>
  <li>Items (int64 id, string description, int64(Sheves FK) homeShelf) </li>
  <li>and Shelves(int64 id, string description)</li>
  </ol>
  
  <p>Is it somehow possible for me to get the shelf description of the item while getting an Item document in one call? Preferably via the C# driver. </p>
  
  <p>I am guessing the answer is no, but since things like Entity Framework have the functionality, I figured I would ask. </p>
