    Hi rakhis,

    Welcome to ASP.NET forums.

    getting error Signalr/hubs 4o4 error.

    Please make sure you call MapSignalR() in Startup.cs, like below.

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

    Besides, please make sure reference the auto-generated SignalR hub script in your web page. And this tutorial shows how to use ASP.NET SignalR 2 with MVC application, you can refer to it, or download the complete sample code to quick setup project.
