Getting "Cannot Access Internal Constructor 'Document' here" on 2.0

Mobile Couchbase Lite

So, I’m on Xamarin trying to use the 2.0 (build 21). I’ve been having this issue, that, when I try to instantiate a new Document like:

var doc = new Document();

I get the following error:

“Cannot Access Internal Constructor ‘Document’ here”.

The Document refers to a internal method, thats why I am unable to use it.

So, what I’m doing wrong here ? I really have no clue.
