Window out of the screen when maximized using WPF shell integration library

Question

I\'m using the WPF Shell Integration Library to create a custom chrome of my wpf app. All is good, but when maximizing the app, 6 or 7 pixels are out of the screen.

Answer 1

In my project, I have CaptionHeight set to 0 and ResizeMode set to CanResizeWithGrip. This is the code I came up with for the proper thickness.

            Thickness maximizeFix = new Thickness(SystemParameters.WindowNonClientFrameThickness.Left +
                SystemParameters.WindowResizeBorderThickness.Left,
                SystemParameters.WindowNonClientFrameThickness.Top +
                SystemParameters.WindowResizeBorderThickness.Top
                - SystemParameters.CaptionHeight,
                SystemParameters.WindowNonClientFrameThickness.Right +
                SystemParameters.WindowResizeBorderThickness.Right,
                SystemParameters.WindowNonClientFrameThickness.Bottom +
                SystemParameters.WindowResizeBorderThickness.Bottom);

I'm just going to use a border like Joe Castro did and then bind the thickness to a property that I update when the window state changes.

Code seems janky but I haven't found another solution yet.
