См. эти обновленная и оптимизированная версия C# 7. Я не хотел удалять версию VB.NET, таким образом, я просто отправил ее в отдельном ответе.

Переходят к обновленной версии

, Кажется, что она не поддерживается, я реализовал один, к вашему сведению, надейтесь это, чтобы быть полезными:

я обновил версию VB, и с этого времени она генерирует событие прежде, чем изменить набор, таким образом, можно сожалеть (полезный при использовании с DataGrid, ListView и намного больше, который можно показать, "Вы верное" подтверждение пользователю), , обновленная версия VB находится в нижней части этого сообщения .

, примите мое извинение, что экран является слишком узким для содержания моего кода, мне не нравится она также.
