【问题描述】:
在 App.xaml 中定义浅色主题 (<AcrylicBrushTintColor="Red"/>)、深色 (<AcrylicBrushTintColor="Orange"/>)。根据这篇文章Changing UWP project's Target Version from 1803 to 1809 disables NavigationView's Acrylic texture - why?,我将以下内容添加到 ShellPage.xaml。当我在浅色和深色主题之间切换时,预期的行为是应用程序NavigationView 控件将具有在红色和橙色之间切换的AcrylicBrush 色调。在下面的定义中,实际行为是保持橙色。
ShellPage.xaml:
<Page.Resources>
<StaticResource x:Key="NavigationViewExpandedPaneBackground"
ResourceKey="MyAcrylicBrush"/>
</Page.Resources>
App.xaml:
<Application

<ResourceDictionary x:Key="Default">
<AcrylicBrush x:Key="MyAcrylicBrush"
