Я пытаюсь интегрировать Windows Box SDK (box.com ) в проект Xamarin. Но я постоянно получаю ошибки при установке необходимых пакетов nuget. Мне удалось установить обычный Box.V2 SDK, но я застрял на Box.V2.JWT SDK. Я получаю эту ошибку:

Could not install package 'System.IdentityModel.Tokens.Jwt 4.0.2.206221351'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.6,Profile=Profile44', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
  

Итак, что я сделал для установки обычного Box SDK, так это изменил профиль Xamarin моего переносимого проекта Xamarin на профиль 44, но я даже не знаю, правильно ли это, и я не могу сделать то же самое для JWT SDK.
Любая помощь действительно ценится

Box SDK не поддерживается на мобильных платформах. Если вы проверите их репозиторий на Github, вы найдете эти поддерживаемые платформы:

• .NET Framework 4.0.3 и выше
• .NET для приложений магазина Windows
• Silverlight 4 и выше
• Windows Phone 7.5 и выше

Он не включает Xamarin.iOS или Xamarin.Android

Проблема на самом деле связана с библиотекой jose-jwt (которая также потерпит неудачу). К сожалению, не существует переносимых совместимых библиотек, поддерживающих построение утверждения JWT с помощью закрытого ключа RSA. На самом деле, именно поэтому мы создали отдельный пакет Nuget для поддержки JWT, а не просто добавили его в библиотеку portable Box.V2.
