Is there a way to get number of connections in Signalr hub group?

Question

Here is my problem, I want to track if user is online or offline and notify other clients about it. I\'m using hubs and implemented both IConnected and IDisconnect interface

Answer 1

There's not way to do this other than counting on your own.

Answer 2

Found how to workaround:

Rewrite ConnectionId, so in every tab you'd have the same ConnectionId:

 public class MyConnectionFactory : IConnectionIdGenerator
    {
        public string GenerateConnectionId(IRequest request)
        {
            return MyUserManager.Instance.CurrentUserID.ToString();
        }
    }

Add to global.asax:

GlobalHost.DependencyResolver.Register(typeof(IConnectionIdGenerator), () => new MyConnectionFactory());

I managed to open as much tabs, as I could and all tabs get notifications.
