Я развернул приложение-функцию Azure в Linux с помощью .NET 8 (dotnet-isolated).
При настройке конфигурации приложения я начинаю с установки базового пути с помощью Directory.GetCurrentDirectory().
Однако во время выполнения (только Azure, а не локально!) файл appsettings.json найти невозможно. Сгенерированный путь представляет собой комбинацию Windows и Linux: '/tmp/functions\standby\wwwroot/appsettings.json'
Почему я наблюдаю такое поведение и как можно это можно исправить?
Ошибка:
Unhandled exception. System.IO.FileNotFoundException: The configuration file 'appsettings.json' was not found and is not optional. The expected physical path was '/tmp/functions\standby\wwwroot/appsettings.json'.

var host = new HostBuilder()
