目前在 WinUI 3 框架中，我们可以通过 ExtendsContentIntoTitlebar 属性来自定义标题栏，然而在自定义标题栏后，点击窗口右键，窗口菜单还是 Win32 样式的。所以在本项目中，我们提供了一种基于 WinUI 风格的窗口菜单实现。

At present in the frame of the WinUI 3, we can through ExtendsContentIntoTitlebar properties to customize the title bar, however after a custom title bar, right click on the window, the window menu or Win32 style. So in this project, we provide a WinUI-style window menu implementation.
