Demostraciones

Este ejemplo muestra cómo desasociar un rol de un usuario mediante el método IOrganizationService.Disassociate. Primero se muestra un fragmento de código que muestra solo las secciones clave de la muestra, seguido por el código de ejemplo completado. Tenga en cuenta que este ejemplo solo se puede ejecutar en un entorno local porque crea un usuario. Sin embargo, la sección del ejemplo que demuestra la desasociación de un rol de un usuario funcionará para todos los entornos.
