WPF合并词典

Question

我正在尝试一起使用MaterialDesginthemes和HandyControl ResourceDictionary，但是在我运行应用程序后，似乎只能识别HandyControl Recourses，我发现应用程序资源只能识别依次词典中的最后一行，任何人都可以帮助您如何帮助解决方案。这个问题

        <ResourceDictionary.MergedDictionaries>
            
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Purple.xaml" />
            <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/SkinDefault.xaml"/>
            <ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/Theme.xaml"/>
               
        </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
