Properties (WinUI3 IDL)

Name	IsDependencyProperty	Description
Window	❌	Microsoft.UI.Xaml.Window property.

When you have Window.ExtendsContentIntoTitleBar(true), the caption buttons often comes out with broken color regarding to theme. This helper fixed it by working as a hidden control and listens to theme change message, and make corresponding changes to caption buttons.

To use, simply put it under a Xaml control (such as Grid) that can accept child contents.

<Window>
    ...
    <Grid x:Name="RootGrid">
        <essential:WindowCaptionButtonThemeWorkaround Window="{x:Bind}" />
        <-- Other contents -->
    </Grid>
</Window>
