How to set the location of WPF window to the bottom right corner of desktop?

Question

I want to show my window on top of the TaskBar's clock when the windows starts.

How can I find the bottom right corner location of my desktop?

I use this code that works well in windows forms app but does not work correctly in WPF:

var desktopWorkingArea = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;
this.Left = desktopWorkingArea.Right - this.Width;
this.Top = desktopWorkingArea.Bottom - this.Height;

Answer 1

This code works for me in WPF both with Display 100% and 125%

 private void Window_Loaded(object sender, RoutedEventArgs e)
 {
    var desktopWorkingArea = System.Windows.SystemParameters.WorkArea;
    this.Left = desktopWorkingArea.Right - this.Width;
    this.Top = desktopWorkingArea.Bottom - this.Height;
 }

In brief I use

System.Windows.SystemParameters.WorkArea

instead of

System.Windows.Forms.Screen.PrimaryScreen.WorkingArea
