Re: how can i list one chatroom 's Contact (General questions)
Hi,
I'm not really sure i understand what exactly the problem is.
If you need number of users in some chatroom you can use Room.Contacts.Count. As for notifications when a user joins a chatroom you can use ContactStatusChanged event where Room parameter will contain Chatroom object for which the change occured.
If i misunderstood what the problem is, please let me know.
