Microsoft OData Client Xamarin не работает
Кто-нибудь знает, если и как клиент Microsoft OData должен работать на Xamarin Droid?
Это пакет NuGet "Microsoft.OData.Client".
Он отлично работает в консольном приложении, даже если пакеты сборки содержатся только в проекте PCL.
Я пытался через генератор кода OData v4.
При запуске на Xamarin вот что я получаю:

Кто-нибудь там с предложением, пожалуйста?

Я не верю, что этот пакет поддерживает Xamarin - со страницы nuget:
Предназначен для.NET Core 5 и.NET Portable Lib с поддержкой.NET 4.0, SL 5.0, Win Phone 8, Win Phone 8.1 и Win 8.
Я бы посоветовал подать проблему с разработчиком библиотеки для получения дополнительной информации об этом, так как это может быть ошибкой, если она поддерживает Xamarin:

В хранилище компонентов есть следующий компонент, который должен работать, хотя с момента его обновления прошло некоторое время:
