C++/CX is a set of extensions to the C++ language that enable the creation of Windows apps and Windows Runtime components in an idiom that is as close as possible to modern C++. Use C++/CX to write Windows apps and components in native code that easily interact with Visual C#, Visual Basic, and JavaScript, and other languages that support the Windows Runtime. In those rare cases that require direct access to the raw COM interfaces, or non-exceptional code, you can use the Windows Runtime C++ Template Library (WRL).
The new model represents the next generation of native C++ programming on Windows. By using it, you can create:
C++ Universal Windows Platform (UWP) apps that use XAML to define the user interface and use the native stack. For more information, see Create a "hello world" app in C++ (UWP).
C++ Windows Runtime components that can be consumed by JavaScript-based Windows apps. For more information, see Creating Windows Runtime Components in C++.
Windows DirectX games and graphics-intensive apps. For more information, see Create a simple UWP Game with DirectX.
