title: Gmail api with .Net CLient library: Missing draft message [400]
body: <p>I'm trying to create drafts in Gmail using the .Net Client Library. I can successfully login and retrieve a list of drafts so the authentication and api are working. Now I need to create an instance of the Draft class and send it to the API. But what does the draft message need to look like? It doesn't matter what I fill in the API explorer on <a href="https://developers.google.com/gmail/api/v1/reference/users/drafts/create" rel="nofollow">https://developers.google.com/gmail/api/v1/reference/users/drafts/create</a>, my draft is always empty.
  Also when doing it from my C# code I need to set the draft.Message.Raw field to something else I get an error:</p>
  
  <pre><code>Missing draft message [400] 
  </code></pre>
