После поисков по всем ссылкам на эту DLL я пришел сюда за помощью.
Я пытаюсь установить sh соединение с SQL сервером, на котором размещена моя моя P C (я знаю, что это не лучшая практика, но решение не до меня). У меня устройство Android, подключенное через док-станцию / USB к моему P C, и я запускаю код на устройстве из Visual Studio 2019 в режиме отладки.
Код компилируется и успешно выполняется на устройстве, пока я не получу свой connection.Open() вызов. Оказавшись там, я получаю несколько исключений DllNotFoundException и SQLException, все ссылающиеся на эту System.Net.Security.Native библиотеку, которая не найдена.
Я прошел через NuGet, добавив все пакеты, которые звучат так, как будто они могут содержать то, что я ищу, но пока не повезло. Я также попытался добавить любые ссылки, которые звучат как-то связанные, но опять же, ничего.
Я также попытался добавить using System.Net.Security.Native;, но VS просто говорит мне
Error CS0234 The type or namespace name 'Native' does not exist in the namespace 'System.Net.Security' (are you missing an assembly reference?)
И удаление «Native» также не решает проблему.
Здесь мы используем журнал из панели «Вывод», просто чтобы вы могли точно увидеть, что он ищет.

Я также приложил скриншот пакетов, которые я установил, а также мои ссылки.
Я также получаю это предупреждение, но я не уверен если это связано.
XA5302: Two processes may be building this project at once. Lock file exists at path: C:\Users\user\Documents\Downloads\XamarinScannerAndroid\XamarinScannerAndroid\XamarinScannerAndroid\obj\Debug\81\.__lock
Боюсь, я исчерпал все свои возможности поиска в Google. Если вам нужно что-то еще (фрагменты кода / скриншоты / et c ..), пожалуйста, дайте мне знать. Спасибо!
Редактировать 1: Также добавлен скриншот моей страницы параметров Android, включая параметры ссылок.
