Я хочу десериализовать граф объектов в моем клиенте Blazor, когда он возвращается из метода API сервера Blazor (аналогично примеру Weatherforecasts).Мне нужно использовать мой собственный метод десериализации с пользовательскими конвертерами, основанными на JsonConverter, потому что мой граф объектов имеет составные объекты, которые реализуют тот же интерфейс.
Все работает за пределами моего проекта блазора, и если я возвращаю граф объекта какстрока для клиента была правильно сериализована.Это десериализация, которая не работает.

РЕДАКТИРОВАТЬ
Думая, что я мог бы переключить сериализаторы Json, я перешел по ссылкам через сообщение: Объявление .NET Core 3.0 Preview 5 на System.Text.Json Docs , что указывает на то, что полиморфное поведение не являетсяподдерживается.В поисках других альтернатив, возможно, TinyJSON ...
EDIT II
TinyJSON работает до определенной степени.При передаче данные включают в себя дополнительные @type свойства, которые стираются с моей стороны, но эй.Оставьте вопрос без ответа в случае простого решения использовать Newtonsoft.
