SignalR - Updating clients from Global.asax

Question

Suppose I have a ChatHub class defined along with a Broadcast method.

I know how to broadcast messages to all clients if one of them sends a message, however how can I send a message to all the clients from Global.asax ?

In other words how do I get access to ChatHub from another class?

Here's a basic sample:

    public class ChatHub : Hub
    {
      public void Broadcast(String reqMessage)
      {
        Clients.broadcast(reqMessage);
      }
    }

Your help is much appreciated.

Where is your ChatHub class? Can you post some more details ? — sandeep, Jul 31 '12 at 20:11
@sandeep, it's a standard hub, any hub. I have added some sample code anyway. — MaYaN, Jul 31 '12 at 20:31

Since SignalR 0.5 you can do this using GlobalHost.ConnectionManager.GetHubContext

Sample

// get gub context
IHubContext context = GlobalHost.ConnectionManager.GetHubContext<ChatHub>();
// broadcast to all clients in this hub
context.Clients.broadcast("Hello World");

Use ConnectionManager, as described here: https://github.com/SignalR/SignalR/wiki/Hubs. Btw, your question is most likely a duplicate of this one.
