Windows Runtime with C++/C#: Anatomy of a WinRT Class

December 30, 2012

The Windows Runtime (WinRT) is based on COM (I referred to it in the past as a “better COM”), which means every method and property must be part of an interface. Also, COM does not support static members (only instance members) and does not easily support parameterized constructors. Inheritance is again an issue in classic COM – the closest thing is COM aggregation, and that’s not really inheritance in the usual sense of the word.Using C++/CX or a .NET language allows creating WinRT types that support methods, properties, constructors and static members, and even events (another feature that is...
