Bunu başarmanın en iyi yolu, windows tarafından yönetilen bir hizmet oluşturmaktır (Nedeni, her bir arama yapılandırmasıyla IIS'de barındırıldığında hizmetinizin ömrünü kontrol edemezsiniz).

Yani yeni bir pencere hizmeti oluşturmak ve wcf hizmeti ve signalr hem ev sahibi (o sadece bir fikir ama kod can benziyor düşünüyorum) olmalıdır:

public class HostWindowService : ServiceBase 
{ 
    public ServiceHost serviceHost = null; 
    public HostWindowService() 
    {  
     ServiceName = "WCFWindowsServiceSample"; 
    } 

    public static void Main() 
    { 
     ServiceBase.Run(new HostWindowService()); 
    } 

    protected override void OnStart(string[] args) 
    { 
     //host wcf service 
     if (serviceHost != null) 
     { 
      serviceHost.Close(); 
     }     
     serviceHost = new ServiceHost(typeof(WCFService));  
     serviceHost.Open(); 

     //host signalr 
     Task.Run(() => SignalRHost());     
    } 

    private void SignalRHost() 
    { 
     try 
     { 
      SignalR = WebApp.Start("http://localhost:8080"); 
     } 
     catch (TargetInvocationException) 
     { 
      WriteToConsole("A server is already running at " + "http://localhost:8080");   
      return; 
     }  
    } 

    class Startup 
    { 
     public void Configuration(IAppBuilder app) 
     { 
      app.UseCors(CorsOptions.AllowAll); 
      app.MapSignalR(); 
     } 
    }  

    protected override void OnStop() 
    { 
     if (serviceHost != null) 
     { 
      serviceHost.Close(); 
      serviceHost = null; 
     } 
    } 
}
