What is a WINMD file?

WINMD files mostly belong to Visual Studio by Microsoft. A WINMD file contains machine-readable metadata used by WinRT (Windows Runtime) application programming interfaces. WinRT APIs use WINMD files to enable language projection for applications on a Windows machine. The \Windows\System32\WinMetadata folder on a system contains the WINMD files for all system-provided WinRT APIs. These files are saved in DLL format and bundled with system and third-party application installers. Visual Studio integrated development environment uses /WINMD C++/C# linker option to generate a binary executable of an application and its WINMD metadata file.
