Extensible Application Markup Language

Extensible Application Markup Language (XAML) is a programming language used to create rich user interfaces in .NET applications. It separates the UI from the program's logic, making it easier for designers and developers to collaborate on project. XAML code defines objects and their properties through markup that closely resembles XML, while an additional code-behind file provides supporting logic written in languages such as C# or VB.NET.
