Спасибо всем, кто предоставил предложения по устранению ошибки «Не удалось загрузить определение API» в моем проекте .NET 8. Я нашел решение проблемы.

Проблема была вызвана тем, что Swagger не поддерживал тип Bitmap в моем DTO. Удалив следующую строку из моего кода, ошибка была устранена:

public Bitmap image { get; set; }

После удаления этой строки пользовательский интерфейс Swagger загрузился правильно, и определение API было успешно отображено.

Еще раз спасибо за вашу помощь и предложения!
