You can still use the Screen class from a WPF app. You just need to reference the System.Windows.Forms assembly from your application. Once you've done that, (and referenced System.Drawing for the example below):

Rectangle workingArea = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;

...works just fine.

Have you considered setting your main window property WindowStartupLocation to CenterScreen?
