CWinRT

CWinRT is a C++ language projection for the Windows Runtime (WinRT). It allows C++ developers to consume and create Windows Runtime APIs using familiar C++ language features. CWinRT is part of the Windows SDK and is designed to provide a modern and efficient way to interact with Windows APIs.

One of the primary goals of CWinRT is to offer a more idiomatic C++ experience compared to previous Windows Runtime C++ templates (WRL). It leverages C++11 and later features, such as templates, lambdas, and smart pointers, to simplify development. CWinRT aims for zero-overhead abstractions, meaning that using CWinRT APIs should incur no performance penalty compared to calling the underlying WinRT APIs directly.

CWinRT generates C++ headers from WinRT metadata. This process allows for compile-time checking of API usage and enables IntelliSense support within development environments. The generated code is designed to be lightweight and efficient. Developers can use CWinRT to access a wide range of Windows features, including UI elements, system services, and hardware capabilities. It is actively developed and maintained by Microsoft as a key component of the Windows development ecosystem.
