ASP.Net Web Forms SignalR Object has no Method

[joe_k]

I added SignalR to an existing ASP.Net 4 Web Forms application. Created a new folder called Hubs and added a Hub like so:\[code\][HubName("UpdatesHub")]public class UpdatesHub : Hub{ public void DownloadUpdates() { // Code Removed }}\[/code\]Added the RouteTable.Routes.MapHubs(); to Application_Start and added the following to the page:\[code\]<script src="http://stackoverflow.com/Scripts/jquery-1.9.1.js"></script><script src="http://stackoverflow.com/Scripts/jquery.signalR-1.0.1.js"></script><script src="http://stackoverflow.com/signalr/hubs"></script><script type="text/javascript"> $(function () { // Declare a proxy to reference the hub. var upd = $.connection.UpdatesHub; // Code Removed // Start the connection. $.connection.hub.start().done(function () { $('#btnDownload').click(function () { upd.server.DownloadUpdates(); }); }); });</script>\[/code\]But whenever I click the button I just get "Uncaught TypeError: Object # has no method 'DownloadUpdates'". I have tried removing and readding signalr via NuGet but can't seem to get this to work, help!
