> Of course Microsoft also had COM, which is/was a stable OO ABI accessible to many languages including C++ and was arguably just a subset of the C++ ABI without templates.
Why the past tense, when COM is the main way Windows APIs have been introduced since Windows Vista, as COM took over Longhorn OO ABI ideas?
I haven't kept up much with Windows programming so lost track at some point of what their current-gen tech is and how it works. WinRT isn't just COM is it. It's custom languages, new app metadata formats and stuff. I don't see IUnknown in any modern Windows code samples.
