WPF XAML Windows 11 Accent Color-CodePudding

Is there a simple way to get the Windows 10 / Windows 11 accent color in XAML?

I looked at many examples, but most of them do not work. I also saw some examples that mimic the color changing behavior in C#, but they do not work in Windows 11.

My code:

<SolidColorBrush x:Key="{x:Static SystemColors.WindowBrushKey}"
    Color="{x:Static SystemParameters.WindowGlassBrush}"/>

I just want to set the Color to windows current accent color.

Thank you.

You should be able to retrieve the accent colour using the UISettings.GetColorValue WinRT API.

Depending on whether you target .NET 5 or an earlier version, you should either set the TargetFramework to net5.0-windows10.0.* or install the Microsoft.Windows.SDK.Contracts NuGet package as described here.

You can then create a SolidColorBrush using the return value of the API:

var color = new Windows.UI.ViewManagement.UISettings()
    .GetColorValue(UIColorType.Accent);
var brush = new SolidColorBrush
    (Color.FromArgb(color.A, color.R, color.G, color.B));

What worked in Windows 10, works also in Windows 11.

OS: Windows 11 Build 10.0.22000.282

VS: 2022 Preview 7.0

WPF: .NET 6

UserLabel.Background = SystemParameters.WindowGlassBrush;

<Style TargetType="{x:Type TextBlock}" BasedOn="{StaticResource TextBase}"
       x:Key="TextColored">
    <Setter Property="FontWeight"
            Value="SemiBold"/>
    <Setter Property="Foreground"
            Value="{x:Static SystemParameters.WindowGlassBrush}"/>
</Style>

This worked without adding any NuGets.
