Xaml

XAML (Extensible Application Markup Language) is a declarative XML-based language used for designing and building user interfaces in various Microsoft technologies, including WPF, UWP, and Xamarin.Forms. As a crucial part of the .NET ecosystem, XAML allows developers to separate presentation logic from business logic, making it easier to create maintainable, scalable, and visually appealing applications, which is why it's a fundamental skill for developers working on Windows and cross-platform projects.
