Windows Runtime
Windows Runtime (WinRT) is a platform-agnostic application architecture and API set introduced by Microsoft for building modern Windows applications. It provides a secure, object-oriented framework that supports multiple programming languages (C++, C#, JavaScript, and Visual Basic) and enables the development of Universal Windows Platform (UWP) apps. WinRT serves as the foundation for Windows 8 and later, facilitating apps that can run across various Windows devices like PCs, tablets, Xbox, and HoloLens.
Developers should learn WinRT when building cross-device Windows applications that require a modern, sandboxed environment with access to system features like sensors, notifications, and live tiles. It is essential for creating UWP apps that target the Microsoft Store, ensuring compatibility with Windows 10/11 and integration with services like Cortana and Azure. Use cases include developing touch-friendly business apps, games, or IoT solutions that leverage Windows' native capabilities while maintaining security and performance.
