ServiceStack.Text и Twitter JSON

Question

Я пытаюсь десериализовать twitter RateLimit Json с ServiceStack.Text. Я создал соответствующий объект DTO (см. Нижнюю часть сообщения) для снятия JSON. Я использовал System.Runtime.Serialization, чтобы переименовать поля в более дружественные имена (я использовал это во многих других объектах DTO из Twitter). При десериализации объекта RateLimitContext десериализуется правильно, однако все элементы в разделе Ресурсы десериализуются до нуля. Я подозреваю, что что-то не так с DataMemberNames для этого конкретного объекта, так как они содержат несколько «специальных» символов. Это ошибка в ServiceStack.Text или я что-то пропустил в своем DTO?
