Authoring Interfaces

Question

It's been a while, but I remember being able to author my own interfaces in vanilla COM for 3rd party implementation. IIRC I made a new project, declared my interfaces in MIDL, and passed out a proxy-stub and a header. Is there a proper way to do this in WinRT/C++, WinUI 3.0 WRC's? Should I just make some vanilla COM interfaces?

Answer 1

I think the proxy/stub sections of these two articles targeting Windows Runtime Components under UWP are the best solutions I'll get. It's essentially the same as the old way of doing it.
