Maximizing (Maximizing) a WPF Window

Question

WPF

I am writing a program with design in the style of Windows 8 (Flat/Metro).
The main window MainWindow.xaml has properties -

WindowStyle="None"
AllowsTransparency="True"

The maximized (expanded) window occupies the entire screen, that is, the windows "taskbar" is also not visible. Is it possible to make some kind of indent from the bottom, or somehow "move" one layer back (as in Photoshop, for example). Thank you in advance

You can use Microsoft.Windows.Shell.WindowChrome.
FakeBorder is needed so that when the window is maximized, the client part does not go beyond the screen. I do not remember the source, I found it somewhere on the msdn forums.

<ControlTemplate x:Key="DefaultWindowTemplate" TargetType="{x:Type Window}">
        <Border Name="FakeBorder" BorderBrush="Green">
            <Border.Style>
                <Style TargetType="{x:Type Border}">
                    <Setter Property="BorderThickness" Value="0"/>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=WindowState}" Value="Maximized">
                            <Setter Property="BorderThickness" Value="{Binding Source={x:Static shell:SystemParameters2.Current}, Path=WindowResizeBorderThickness}"/>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </Border.Style>
            <Border Name="WindowBorder" 
                Background="{TemplateBinding Background}" 
                BorderBrush="{TemplateBinding BorderBrush}"
                BorderThickness="{TemplateBinding BorderThickness}" Margin="0">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="{StaticResource grdlenWindowCaptionHeight}" />
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>
                    <Border Name="TitleBorder" Background="{TemplateBinding Background}" Margin="{TemplateBinding Margin}" >
                        <Grid >
                            <Grid.ColumnDefinitions>
