WPF - изменить стиль выбора для списков в приложении WPF на стиль по умолчанию Windows 7

Question

У меня проблема в приложении WPF со стилем выделения элементов списка. Каждый список в WPF имеет темно-синий цвет фона и белый цвет текста.

1. Почему стиль выбора по умолчанию в Windows 7 (например, выбор файла в Проводнике Windows) НЕ является стилем выбора по умолчанию в приложении WPF в Windows 7?

2. Как изменить стиль выделения в WPF на стиль Windows 7 Aero по умолчанию?

Пока что это есть в моем глобальном словаре ресурсов. Но мне все еще нужна граница с закруглением вокруг кисти, чтобы она выглядела похожей. Любая идея, как расширить это или любые другие предложения о том, как я могу применить стиль выбора Windows 7 по умолчанию?

У меня есть запись в блоге, которая описывает, как применить Windows 7 к ListBox здесь . ListView и TreeView также рассматриваются, но не полностью соответствуют тематике Windows 7.
