尝试在 Window 倾斜条上覆盖堆栈面板。使 WindowStyle="None" ResizeMode="NoResize" 并调整控件的边距（MAKE TOP NEGATIVE OF STACKPANEL）以覆盖标题栏上的窗口堆栈面板。

<Window x:Class="WPF_UI.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
       WindowStyle="None" WindowStartupLocation="CenterScreen" ResizeMode="NoResize"  Width="920" Height="600" >

<Grid>....other stack panels....
**Here i have take stack panel to overwrite on window title bar.**
<StackPanel Margin="0,-566,0,5" Grid.ColumnSpan="3" Height="25" DataContext="{Binding}">
                <StackPanel.Background>
                    <LinearGradientBrush>
                        <GradientStop Color="White" Offset=".2" />
                        <GradientStop Color="Gray" Offset=".5" />
                        <GradientStop Color="Black" Offset="1" />
                    </LinearGradientBrush>
                </StackPanel.Background>
                <TextBlock HorizontalAlignment="Left" VerticalAlignment="Center" Margin="1,5,0,0"> APPLICATION NAME
                </TextBlock>
                <Button Content="Close" Margin="860,-17,0,0" VerticalAlignment="Center" HorizontalAlignment="Left" Name="btnClose" Width="40" >
                    <Button.Background>
                        <LinearGradientBrush StartPoint="0,0" EndPoint="0,2">
                            <GradientStop Color="Black" Offset=".2" />
                            <GradientStop Color="Gray" Offset=".5" />
                            <GradientStop Color="White" Offset="1" />
