body: <p>How can I save document in mongo in camel case? Now i am trying to save this:</p>
  
  <pre><code>  "parent_template_id": "5aa7822ba6adf805741c5722",
    "type": "Mutable",
    "subject": {
      "workspace_id": "5-DKC0PV8U",
      "additional_data": {
        "boardId": "149018",
      }
  </code></pre>
  
  <p>but boardId transform into board_id in db (snake case).
  This is my field in c#:</p>
  
  <pre><code>[BsonElement("additional_data")]
  [BsonIgnoreIfNull]
  public Dictionary&lt;string, string&gt; AdditionalData { get; set; }
  </code></pre>
