Class ClientAreaBorder

Namespace
Wpf.Ui.Controls
Assembly
Wpf.Ui.dll

If you use WindowChrome to extend the UI elements to the non-client area, you can include this container in the template of Window so that the content inside automatically fills the client area. Using this container can let you get rid of various margin adaptations done in Setter/Trigger of the style of Window when the window state changes.

Remarks

If you use a WindowChrome to extend the client area of a window to the non-client area, you need to handle the edge margin issue when the window is maximized. Use this property to get the correct margin value when the window is maximized, so that when the window is maximized, the client area can completely cover the screen client area by no less than a single pixel at any DPI. TheGetSystemMetrics(SM) method cannot obtain this value directly.
