What is XAML?

XAML (Extensible Application Markup Language) is a declarative markup language developed by Microsoft. It is most commonly used for creating user interfaces in .NET-based applications, particularly those using WPF (Windows Presentation Foundation), UWP (Universal Windows Platform), and Xamarin.Forms. XAML describes the visual structure of an application, separating the UI definition from the application logic, typically written in a language like C# or VB.NET. It allows developers to design and prototype UI elements easily, handle data binding, and manage resources.
