Комментарии

ClaimSet После создания класса его нельзя изменить.

Изучение содержимого определенных ClaimSet типов утверждений является общей задачей при использовании авторизации на основе утверждений. Чтобы проверить наличие определенных утверждений в ClaimSet, используйте метод FindClaims. Метод обеспечивает лучшую производительность, чем итерацию непосредственно над ClaimSet.
