Я добавил пакет от Nuget для .NET Standard 2.0
После этого я получил ошибку сборки ниже:

Я нашел решение и исправил его, добавив <ImplicitlyExpandDesignTimeFacades> false </ImplicitlyExpandDesignTimeFacades> в файл .csproj
Мой вопрос: что такое ImplicitlyExpandDesignTimeFacades и что он делает?
Почему Visual Studio ищет библиотеки в папке "Reference Assemblies"?(Разве это не во время разработки?)
почему они помещают одни и те же библиотеки в другое место ("Справочные сборки")?
не должно визуально загружать студии .Net библиотеки из "Каталог Windows?
как можно иметь разные версии в разных местах?
Извините за большое количество вопросов.Я думаю, что они не являются отдельными.
