WCF控制台应用程序上的性能问题

Question

There is a WCF service that is hosted in a .Net Console application. The client creates a duplex channel to the service that has a callback. It calls the service in this way:

var task = Task<object>.Factory.FromAsync(clientRay.Proxy.BeginCalc, clientRay.Proxy.EndCalc, lst_RaySrvcDetails, state);

And here is the Main method of the service Console app:

static void Main(string[] args)
{
     ServiceHost srvcHost = new ServiceHost(serviceInstance, uriBase);
     //
     //Here the service is hosted
     //

     while(true)
     {
        ;
     }
}  

And the MyService.cs receives the call in the below method:

public IAsyncResult BeginCalc(List<MBSWaldram.DataAccessLayer.Framework.ServiceDetails> input,
                    AsyncCallback callback, object state)
{
   calcInput = input;

   // Create a task to do the work
   var task = Task<object>.Factory.StartNew(this.CalcTasks, state);

   return task.ContinueWith(res => callback(task));
}

Now the CalcTasks method, where the actual task is run, is showing less performance compare to have it on a WCF Windows Form application. One of the reason I can think of is the way I have used while(true){;} infinite loop so that the application doesn't terminates and waits for the call from the client. Not sure this the best of doing it. For some reason I can't use Windows Form Application.

I appreciate if anyone could shed some light in why there is a performance issue here. Thanks.

while (true) {;} is really unlucky construction. In Console application take Console.ReadLine() instead. The application will wait until Enter press.
