Note: this is in the context of 'programmatically extending Office/M365', I don't think the OP was referring to COM in general.

COM is at the base of WinRT, which is pretty much _not_ deprecated.

Indeed, in what concerns Windows itself, COM has been the cornerstone of Windows APIs since Vista.

If only they would improve the tooling, instead of like I am doing COM in Windows 95 with Visual C++ 5 kind of experience, because every time there is some project to improve the experience it gets killed after a while, and we're back to yet another C++ framework with the MIDL command line compiler.
