services.AddScoped<IWishListItemRepository, WishListItemRepository>()в чем разница использования public new void hello() и public void hello()
если результат один и тот же для обоих, я понимаю, что правильно использовать с new, но меня интересует почему мы так делаем?
Посоветовали смотреть в сторону C#, если хочу работать только с Windows.
В тоже время в С++ шаблоны "размножаются" в коде.
Есть ли смысл изучать его ради маленьких в пару страниц сайтов (но всё же серверным функционалом, не просто "отдать html по ссылке")?
Какие у него есть киллер-фичи, облегчающие жизнь?
я слегка пересрался от вида "пустого проекта asp net" в visual studio.

}в коде происходит полный выход из метода UploadPhotos(), хотя у меня там еще приличная часть кода должна исполниться. Прыжок происходит как в пошаговом так и в обычном режиме.
