Question

How does the SignalR handle client disconnection? Am I right if I state the following?

In SignalR 1.0, the SignalR.Hubs.IConnected and SignalR.Hubs.IDisconnect are no longer implemented, and now it's just an override on the hub itself:

public class Chat : Hub
{
    public override Task OnConnected()
    {
        return base.OnConnected();
    }

    public override Task OnDisconnected()
    {
        return base.OnDisconnected();
    }

    public override Task OnReconnected()
    {
        return base.OnReconnected();
    }
}
