Миграция Net48 на net60: не удалось загрузить файл или сборку «System.Runtime, Version=6.0.0.0...» ⇐ C#

[Anonymous]

Я переношу свое приложение с net48 на net60. Во время миграции мне нужно обновить свой собственный пакет NuGet для поддержки net60 и добавить его в свое приложение, но во время сборки я получаю сообщение об ошибке:

WcfWrapperGenerator.targets(36, 5): не удалось загрузить файл или сборку
'System.Runtime, Version=6.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' или одну из ее зависимостей.
Системе не удается найти указанный файл.

фактическое место ошибки (строка 36):


Как это исправить?
Кроме того, я вижу ошибку при попытке получить анализ кода:
