Answer 1

Make sure you add

app.MapSignalR();

inside startup.cs and Configuration method, like this:

 public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
    }

For Asp.net Core

Add

services.AddSignalR();

in ConfigureServices methode in your startup.cs

And add

app.UseSignalR(routes =>
            {
                routes.MapHub("/chatHub");
            });

in Configure methode in your startup.cs
