Get Current Screen Width

Question

Hello, what I achieved so far:
1. Added a reference to System.Windows.Forms.
2. Added using System.Windows.Interop;.
3. Right after namespace I have defined the following extension, which I have found on StackOverflow; it didn't work when placed inside MainWindow class:
    static class ExtensionsForWPF
        public static System.Windows.Forms.Screen GetScreen(this Window window)
            return System.Windows.Forms.Screen.FromHandle(new WindowInteropHelper(window).Handle);
4. Inside MainWindow declared
            System.Windows.Forms.Screen CurrentScreen = ExtensionsForWPF.GetScreen(this);
5. Successfully compiled.
Problem: When I try to use CurrentScreen.Width inside MainWindow I get this error:
Error 1
'System.Windows.Forms.Screen' does not contain a definition for 'Width' and no extension method 'Width' accepting a first argument of type 'System.Windows.Forms.Screen' could be found (are you missing a using directive or an assembly reference?)
How do I use it then???
