In SignalR 2 you could do something like this (taken from my blog):

```
var stockTickerHub = GlobalHost.ConnectionManager.GetHubContext<StockTickerHub>();

```

That allows you to get a reference to the SignalR hub from outside the hub (e.g. from a stock ticker thread).

This does not seem to be available in SignalR 3. How do you achieve the equivalent functionality in the new and upcoming SignalR?
