How to get current user from IHubContext in SignalR?

Question

Suppose in some class library I have access to a specific HubContext:

IHubContext ctx = connectionManager.GetHubContext<MyAwesomeHub>();

How do I get access to the current authenticated .User property?

Answer 1

You can't. The GetHubContext method is normally used for sending messages from a background thread to a client (or many/all clients) so by definition won't have a SignalR user backing it.
