В C# не работает Text Edit

Приветствую, начал изучать C# с нуля по книге "Изучаем C#" Эндрю Стиллмена. В книге все происходит в VS2012 for Windows 8. Соответственно на компьютер именно эту версия и поставил, чтобы мог выполнять все действия буквально.
На одном этапе необходимо изменить текст через Edit Text контекстного меню. И я получаю вот это сообщение с ошибкой:
