Getting exceptions on SignalR connection start method

I am creating an application using SignalR. I have followed all configurations required to start working with SignalR like below. Startup Class

[assembly: OwinStartup("TestingConfiguration", typeof(UsingFoundation.Startup))]

namespace UsingFoundation
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            string sqlConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["ProjectDBEntities"].ConnectionString;
            if (!string.IsNullOrWhiteSpace(sqlConnectionString))
            {
                GlobalHost.DependencyResolver.UseSqlServer(sqlConnectionString);
            }
            app.MapSignalR();
        }
    }
}

AppSettings

<appSettings>
    <add key="owin:appStartup" value="TestingConfiguration" />
  </appSettings>

Hub Class

namespace UsingFoundation
{
    [HubName("chathub")]
    public class ChatHubClass : Hub
    {
        public void Hello()
        {
            Clients.All.hello();
