c++/cx

C++/CX (Visual C++ component extensions) is a set of language extensions that enable native C++ developers to work with the Windows Runtime (WinRT) more easily. WinRT powers the Universal Windows Platform (UWP), allowing applications to run across Windows devices such as Xbox, PCs, HoloLens, and phones. While WinRT APIs are readily accessible from managed languages like C#, native C++ developers previously had to write complex COM code or use C++/CX. C++/CX provides automatic reference counting and helps C++ understand WinRT metadata, simplifying UWP and traditional desktop development. However, modern projects often prefer C++/WinRT, a newer, standard C++ alternative.
