Usé la respuesta de Lars para administrar mi servicio y funciona bien. Pero necesitaba pasar argumentos al servicio y me tomó un par de horas descubrir cómo hacerlo. Así que decidí publicar una clase alterada con la capacidad de iniciar el servicio con parámetros:

InstallService
con un nombre de servicio en particular, si estoy consultando laServiceName
propiedad deServiceBase
dentro de mi servicio, siempre me devuelve algo más. ¿Alguna sugerencia sobre cómo obtener ese nombre desde el interior del servicio?
