I was looking at the samples (e.g. HelloWorld.cs) and
c# compiler was reporting an ambiguity between
So i downloaded sources, and found that the Document
protected boolean open/close
public void open()/close()
I fixed it by renamig the boolean variables as _open
and _close where required, rebuilt the project and now
it works fine.
I never worked with J# before so don't know if I did it
right. Anyway, I hope this helps.
