Comentarios

Para obtener el objeto de un recurso, el Configuration código debe tener privilegios de lectura en todos los archivos de configuración de los que hereda la configuración. Para actualizar un archivo de configuración, el código también debe tener privilegios de escritura para el archivo de configuración y el directorio en el que existe.
