Communication from client to WCF for user session management RRS feed

  • Question

  • User-1070963513 posted

    I am trying to set up a kind of heartbeat system where users on my .net site will send a message to my WCF service through signalR, so that the service knows they are still online. When the service does not receive a ping it will remove their session information from the database. However i cannot work out how to get my site to connect to the signalR hub. At the moment i just get a 404 not found error.


            var connection = $.hubConnection();
        connection.url = "http://localhost:63782/session";
        var hubProxy = connection.createHubProxy('SessionHub');
        connection.start({ jsonp: true }).done(function () {

    SessionHub.cs (inmy WCF project)

        using Microsoft.AspNet.SignalR;
    namespace VisionMobileService.Classes
        public class SessionHub : Hub
            public void CheckSession(string SessionID)

    Startup.cs (in my wcf project)

        using System;
    using System.Threading.Tasks;
    using Microsoft.Owin;
    using Owin;
    using Microsoft.Owin.Builder;
    using System.Web.Routing;
    using VFF.VisionTouch.DataService.Classes;
    [assembly: OwinStartup(typeof(VisionMobileService.Classes.Startup))]
    namespace VisionMobileService.Classes
        public class Startup
            public void Configuration(AppBuilder app)
               // app.MapSignalR("/session", new Microsoft.AspNet.SignalR.HubConfiguration() { EnableJSONP = true });

    can anyone see where i am going wrong? I should also note that I am planning on changing it to a persistent connection once I get the basics working.
