I'm using Trello.net to manage Trello boards through their API.
One thing I need to do, is change a new board I created to be public.
This code doesn't seem to work
myBoard.Prefs.PermissionLevel = PermissionLevel.Public;
trello.Boards.Update(myBoard);
As of release 0.5.5-beta Trello.NET supports this. Use
Trello.Boards.ChangePermissionLevel
. More info here.
