Как вернуть связанные сущности в web api и вызвать web api из отдельного приложения MVC

---

Как я могу вернуть сущность с ее связанными сущностями в методе Web API и вызвать ее из приложения MVC?

У меня есть веб-API, в котором я возвращаю сущность Person, а также возвращаю все политики, связанные с этой сущностью person.

Таким образом, у человека может быть один или несколько полисов.

До сих пор я могу сделать это в своем контроллере Web API.

Проблема заключается в вызове моего веб-API в отдельном приложении MVC.

В настоящее время я могу вернуть только запись Person в моем приложении MVC, я изо всех сил пытаюсь вернуть Person и все связанные с ним политики в моем приложении MVC.

В моем представлении MVC .cshtml я вызываю ViewModel для передачи данных во все поля веб-API.

Что я уже пробовал:

Я попытался использовать прилагаемый код, но он не может десериализовать данные в моем приложении mvc.project
