title: MongoDB Insert Entity vs a BsonDocument using via C# Driver
body: <p>I am using the .NET MongoDB driver to insert values into my collection in MongoDB .</p>
  <p>I noticed when I insert an entity the objects get stored as simple columns like in the second document below where as when I used a BsonDocument to insert documents they get inserted as an object under the _v column in the first document below.</p>

  <p>Can someone explain whats the difference between the two?</p>
  <p>Also is it possible to insert the BsonDocument like in the second document via the .NET driver? In my case I have to build the document Dynamically since I dont have a concrete entity to insert with.</p>
