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
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.
