.ToJson() ignores null values using MongoDB C# Driver

Question

Using the MongoDB C# driver, the following code gives me { } in the json variable. It seems to ignore the null value in its serialization.

var document = new BsonDocument{{"x", null}};
var json = document.ToJson();

However I want json to be { "x": null }. Can I set some option for it to serialize null values?

BsonDocument is what is ignoring the null, but AntonioOtero's answer is correct way to solve it — Ted Elliott

Basically, you have to use BsonNull.Value.
