Returns: A xtd::drawing::rectangle that represents the size, in pixels, of the working area of the screen.

Remarks: The xtd::forms::system_information::working_area property indicates the bounds of the screen that can be used by applications. The working area is the desktop area of the display, excluding taskbars, docked windows, and docked tool bars.; xtd::forms::system_information::working_area always returns the work area of the primary monitor. If you need the work area of a monitor in a multiple display environment, you can call one of the overloads of xtd::forms::screen::get_working_area.
