Reference for Windows Runtime API namespaces

Windows Runtime (WinRT) is a set of application programming interfaces (APIs) that allow developers to create applications for the Windows operating system, designed to be language-independent so that they can be used from various programming languages, including C++, C#, or JavaScript. WinRT APIs are based on the Component Object Model (COM) and provide a modern, object-oriented approach to Windows development. WinRT APIs enable access to a wide range of Windows features and services, such as file handling, networking, and user interface elements.
