WinRT (short for Windows Runtime) is the set of APIs used to create Windows Store apps. WinRT APIs are defined in .winmd files that encode metadata using the ECMA 335 format, which is very similar to that of .NET assemblies. WinRT .winmd files do not contain code (this is part of the underlying Windows 8 OS), only metadata.
