There is no such syntax. The Windows Service is hosted in a different way and is run by Windows Service Controller. To get to this point, you need to install you Service application in a proper way. Then you need to use system "Services" applet (services.msc) to start the service.
In order to install service, you need to program your service application "installable". In fact, you can develop your application the way it can be used as an interactive application and a Windows Service, depending on how it is run. If you do that, you can include installation code and optionally the code working with the Service Controller to start/stop/restart your service. These two chores can be implemented in the interactive part of your application (or a separate application, of course).
