SignalR: Hub OnConnected not called if no client methods

Question

I am writing a game in SignalR. The idea is that you connect with your laptop, which will be used as \"display\" and then you connect with your smart phone and that will be used

Answer 1

That's by design. If you don't have any subscriptions to the hub then that particular client can't won't get any messages from server to client. You can still invoke methods on the hub.
