If you use a custom dependency resolver with SignalR, you can no longer use GlobalHost unless you modify it: GlobalHost.DependencyResolver = new AutofacDependencyResolver(container); IHubContext hubContext = GlobalHost.ConnectionManager.GetHubContext<MyHub>(); // A custom HubConfiguration is now unnecessary, since MapSignalR will // use the resolver from GlobalHost by default. app.MapSignalR(); If you don’t want to modify GlobalHost, you will … Read more
SignalR connections (including the connection underlying all Hub operations for a client) do not support Session state. You could enable it if you wanted to but we’d strongly recommend against it as session state access serializes requests for a given client, meaning you won’t really get the benefit from SignalR duplex messaging anymore, as one … Read more

So try it with: public Task Join() { string username = Context.User.Identity.Name; //find group based on username string group = getGroup(username) return Groups.Add(Context.ConnectionId, group); }
