У меня запущено приложение Blazor. net стандарт 2.0 и WebAPI, работающий в. NET core 3.1 и стандартная библиотека классов.
Приложение скомпилировано и работает до вчерашнего дня, когда оно, казалось бы, просто остановил компиляцию с ошибкой
Невозможно запустить ваш проект. Свойство «RunCommand» не определено.
Тип вывода для Blazor и WebAPI - это консольное приложение, и у меня установлено несколько проектов запуска - сначала WebAPI и Blazor.
Я не думаю, что что-то изменилось, чтобы вызвать эту ошибку.
Есть идеи, что может вызвать это?
ОБНОВЛЕНИЕ
После удаления объекта obj и bin-файлы, теперь я получаю следующую ошибку в VS -
