WPF 최대화 문제

문제:
    WindowStyle=None으로 지정하고 커스텀 WindowChrome을 사용하면 최대화 시 윈도우가 좌측 상단으로 삐져나가고 우측 하단에 빈 공간이 생김

해결:

        protected override void OnSourceInitialized(EventArgs e)
        {
            base.OnSourceInitialized(e);
            ((HwndSource)PresentationSource.FromVisual(this)).AddHook(HookProc);
        }

        public static IntPtr HookProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
        {
            if (msg == WM_GETMINMAXINFO)
            {
                // We need to tell the system what our size should be when maximized. Otherwise it will
                // cover the whole screen, including the task bar.
                MINMAXINFO mmi = (MINMAXINFO)Marshal.PtrToStructure(lParam, typeof(MINMAXINFO));

                // Adjust the maximized size and position to fit the work area of the correct monitor
                IntPtr monitor = MonitorFromWindow(hwnd, MONITOR_DEFAULTTONEAREST);

                if (monitor != IntPtr.Zero)
                {
                    MONITORINFO monitorInfo = new MONITORINFO();
                    monitorInfo.cbSize = Marshal.SizeOf(typeof(MONITORINFO));
                    GetMonitorInfo(monitor, ref monitorInfo);
                    RECT rcWorkArea = monitorInfo.rcWork;
                    RECT rcMonitorArea = monitorInfo.rcMonitor;
                    mmi.ptMaxPosition.X = Math.Abs(rcWorkArea.Left - rcMonitorArea.Left);
                    mmi.ptMaxPosition.Y = Math.Abs(rcWorkArea.Top - rcMonitorArea.Top);
                    mmi.ptMaxSize.X = Math.Abs(rcWorkArea.Right - rcWorkArea.Left);
                    mmi.ptMaxSize.Y = Math.Abs(rcWorkArea.Bottom - rcWorkArea.Top);
                }

                Marshal.StructureToPtr(mmi, lParam, true);
            }

            return IntPtr.Zero;
        }

        private const int WM_GETMINMAXINFO = 0x0024;

        private const uint MONITOR_DEFAULTTONEAREST = 0x00000002;

        [DllImport("user32.dll")]

        [DllImport("user32.dll")]
        private static extern bool GetMonitorInfo(IntPtr hMonitor, ref MONITORINFO lpmi);

        [Serializable]
        [StructLayout(LayoutKind.Sequential)]
        public struct RECT
        {

        }

            public RECT rcWork;
            public uint dwFlags;
        }

        [Serializable]

        public struct POINT
        {
            public int X;

            public POINT(int x, int y)
            {
                this.X = x;
                this.Y = y;
            }
        }

            public POINT ptMinTrackSize;
            public POINT ptMaxTrackSize;
        }

기타:
    이건 사용자가 직접 해결할 문제가 아니라 WPF쪽에서 고쳐줘야 하는 것 아닌가?
