I've been using something very similar for testing. I'm still getting crashes when native vcruntime140 and builtin vccorlib140 is used.
Ah, I was running the code against builtin DLLs only. FWIW, there's some additional bookeeping `_CxxThrowException` does when a `TYPE_FLAG_IUNKNOWN` exception is thrown, which depends on the last field in `set_exception_inner` being a valid function pointer. I opened !9306 which tries to do this.
I think it's better to keep cxx.h file identical in all the dlls. How about introducing a new macro `DEFINE_WINRT_CXX_TYPE` for WinRT? I'm thinking about something along these lines:

Yes, it'll also make the RTTI declarations a little clearer. I'll attempt this in the latest revision, thanks
