           When developing a WPF application with .NET 9 or later, you can ensure your app matches the sleek, modern look of Windows 11. The new Fluent theme for WPF introduces a contemporary Windows 11 aesthetic to WPF applications, complete with integrated Light/Dark mode and system accent color support. This update not only modernizes the appearance of your app but also enhances user engagement by providing a polished and cohesive user experience.
       - question: My team is comfortable building WinForms apps, and it suits our needs. Should we consider migrating to WinUI or another framework?
