Service debugging in Windows 8

Prior to Windows 8 you could debug your services by using statements like:

Debugger.Launch();

Now this is being simply ignored. What is reason of that?

Debugger.Launch() would call application with visual user interface. In Windows 8 this is impossible because services can't interact with desktop and run in interactive mode.

To debug service code we added the following code to OnStart method:

while (!Debugger.IsAttached) // waiting until debugger is attached
{
    RequestAdditionalTime(1000);  // prevents the service from timeout
    Thread.Sleep(1000);  // gives you time to attach the debugger
}
