calling SignalR hub from WebAPI controller

I'm using MVC 5, Signal R 2.0.1, and WebAPI 2, and have a simple hub set up named ExportHub

public class ExportHub : Hub
{
    public void Send(string name, string message)
    {
        // Call the addNewMessageToPage method to update clients.
        Clients.All.addNewMessageToPage(name, message);
    }
}

I'm attempting to call this from WebAPI so the UI can be updated.

var hubContext = GlobalHost.ConnectionManager.GetHubContext<ExportHub>();

But within hubContext I don't see any reference to Send or addNewMessageToPage. How do I gain access to the methods within the hub?

Try to make your Send method static, and then call hubContext.Send(string, string)

You will not be able to call any methods of specified hub. GetHubContext only returns a IHubContext of specified T Hub. Instead of calling Hub methods you should directly invoke method from your web api method to client like

Clients.All.addNewMessageToPage(name, message);
