SystemXaml

System.Xaml is a .NET Framework assembly that provides a core implementation of the XAML (Extensible Application Markup Language) language. XAML is an XML-based language developed by Microsoft to define user interfaces and application objects in a declarative way. The System.Xaml assembly is fundamental for frameworks that utilize XAML, such as Windows Presentation Foundation (WPF) and Windows Workflow Foundation (WF). It enables the parsing, serialization, and manipulation of XAML documents.

The primary functionality offered by System.Xaml includes the XAML reader and writer APIs, which allow applications to process XAML content. It also provides a type converter system that maps XAML types to their .NET counterparts, facilitating the creation and manipulation of objects from XAML. Furthermore, System.Xaml handles object graph creation, property setting, event handling, and resource management within the XAML processing pipeline. It plays a crucial role in the separation of concerns between UI design and application logic, allowing designers to work with XAML files while developers implement the underlying code. This assembly is a foundational component for modern .NET UI development, enabling rich and dynamic user experiences through declarative markup.
