    SignalR Chat

    Hi All.

    I'm using umbraco v7.0. I would build project chat with SignalR microsoft. The structure of project: App(web umbraco) -View include js files - 

    <script src="/Scripts/jquery.signalR-2.2.0.min.js"></script>
    <script src="/signalr/hubs"></script>
    MVC(build controller) - ChatHub file

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

    -Startup file public class Startup { public void Configuration(IAppBuilder app) { // Any connection or hub wire up and configuration should go here app.MapSignalR(); }
    }

    When i run page : $(function () { // Reference the auto-generated proxy for the hub.
    var chat = $.connection.chatHub; }); error:

    <script src="/signalr/hubs"></script>

    404 not found.

    Please help me fix this issue.

    Thanks

    Hi,

    Do you have a Configuration method?

    [assembly: OwinStartup(typeof(SignalRProgress.Startup))]
namespace SignalRProgress
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // Any connection or hub wire up and configuration should go here
            app.MapSignalR();
        }
    }
}

    Did you add '~/signalr/hubs' path to the umbraco reserved paths ?

    <add key="umbracoReservedPaths" value="/umbraco/,/signalr/" />

    Thanks, Alex

    Would also love to know what the problem was and how it was resolved since I get the same behaviour on a 7.3.0 site (working fine on 7.2.8)

    I had the same problem with 7.3.0, got it solved now. As far as I could tell it has to do with the fact that Umbraco uses OWIN since 7.3.0. See web.config, it has an entry

    <add key="owin:appStartup" value="UmbracoDefaultOwinStartup" />

    Before 7.2.8 it didn't use this. You probably have your Startup.cs class to register the use of SignalR? The startup class doesn't get called in the new 7.3.0 scenario. To fix this, create a class that inherits from UmbracoDefaultOwinStartup and add the SignalR usage. Change the web.config entry to the friendly name you give your OWIN class.

    <add key="owin:appStartup" value="TestStartup" />

    With my Startup.cs looking like this:

    using System;
using System.Threading.Tasks;
using Microsoft.Owin;
using Owin;
using Umbraco.Web;

[assembly: OwinStartup("TestStartup", typeof(WebApplication1.Startup))]

namespace WebApplication1
{
    public class Startup : UmbracoDefaultOwinStartup
    {
        public override void Configuration(IAppBuilder app)
        {
            base.Configuration(app);
            app.MapSignalR();
        }
    }
}

    HTH
