A window is a top-level display container in .NET MAUI. When a desktop app launches, its initial window hosts the application's MainPage; additional windows can host other pages. section 10.3.3
Open an About window
Create a Window around an AboutPage, configure its title and dimensions, then display it through Application.Current.OpenWindow(newWindow). This keeps AboutPage as an ordinary ContentPage while showing it separately from the main window.
