How to make full screen mode, without covering the taskbar using :wpf c#

Question

I need to change windows taskbar in my WPF application. For that I set WindowStyle=\"None\", which means to disable the windows taskbar, and make custom taskbar

Answer 1

Proposed solution worked for me but still need to correct pixel to dpi setter values for window to have correct size regardless user settings:

in xaml :

WindowStyle="None" WindowState="Maximized" ResizeMode="NoResize"

in code :

public MainWindow()
{
    InitializeComponent();
    var graphics = System.Drawing.Graphics.FromHwnd(IntPtr.Zero);
    var pixelWidth = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width ;
    var pixelHeight = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;
    var pixelToDPI = 96.0 / graphics.DpiX ;
    this.Width = pixelWidth * pixelToDPI;
    this.Height = pixelHeight * pixelToDPI;
    this.Left = 0;
    this.Top = 0;
    this.WindowState = WindowState.Normal;
}
