Comentarios

El SupportsInterface método permite que la instancia de proxy actual implemente interfaces COM adicionales en nombre del objeto de servidor que representa la instancia actual. El método actual genera la interfaz solicitada y devuelve un puntero a ella. Los tipos de interfaces COM que puede generar este método dependen del tipo de proxy, que a su vez puede depender del tipo del objeto de servidor que representa la instancia de proxy actual.
