Wpf 使用材料设计工具包，在Mahapps Metro窗口don'；我不能正常工作

上下文：我正在使用Mahapps.Metro弹出式按钮和材料设计工具包

问题：当

弹出按钮

打开时，它未按指定位置定位。例如，如果我将

弹出按钮

设置为位于

窗口的
底部
，它将位于垂直中心

我已经设置了App.xaml来支持Mahapps和材质设计。我还对主题和口音进行映射，以获得一致的体验

我采用了mdwiki中显示的配置。我有一个地铁窗口，我的应用程序使用了各种控制与Mahapps和材料设计风格-没有任何问题。只有弹出按钮不能正常工作

为了隔离问题，我将我的应用程序减少到最低限度。此外，我还使用了Material Design Mahapps演示应用程序中的示例弹出按钮。

虽然演示应用程序运行良好，但它在我的应用程序上下文中不起作用。

如果我将Mahapps MD兼容性的内容从App.xaml中删除，弹出按钮可以正常工作，但当然没有MD主题

App.xaml：

尝试了几个小时后，我仍然不知道问题出在哪里。任何暗示都将受到高度赞赏

致以最良好的祝愿，
Marcus
MaterialDesignThemes的当前版本不适用于MahApps v1.4.1。我会把更新推到回购协议上。太好了！谢谢！新版本发布后，我会尽快试用。嗨，伙计们，我已经合并了@punker76的更改，并推到了nuget：嗨，我在我的项目中加入了0.0.9。在启动时，我遇到了一个XamlParseException，内部异常表示加载程序集MahApps.Metro时出现问题，因为清单定义和程序集引用之间不匹配。我改回0.0.8，异常消失了。（{“Die Datei order Assembly\”MahApps.Metro，PublicKeyToken=null\"现在的MaterialDesignThemes版本不适用于MahApps v1.4.1。我将对repo进行更新。太好了！非常感谢！我会在新版本发布后立即试用。嗨，伙计们，我是erged@punker76的更改，并推送到nuget：嗨，我将0.0.9拉到我的项目中。在启动时，我有一个XamlParseException，内部异常表示加载程序集MahApps.Metro时有问题，因为清单定义和程序集引用之间不匹配。我改回了0.0.8，异常消失了({“Die Datei order Assembly\”MahApps.Metro，PublicKeyToken=null\”或“davon wurde nicht gefunden。Die gefundene的定义不适用于组装。
