Excel-DNA NativeAOT: can a separate functions DLL be hot-swapped, or must all exported functions be compiled into the main AOT add-in?

[Melih Özcan]

Hi,
I’m trying to use Excel-DNA NativeAOT with a split architecture where the host add-in is stable but the Excel function assembly can be updated independently. (Triggered from within AutoOpen())

However, NativeAOT appears to need the Excel function registrations at build time, and .NET NativeAOT also does not support dynamic assembly loading. Given that, is a “hot-swappable ExternalLibrary containing Excel functions” fundamentally unsupported in NativeAOT?

If unsupported, what is the intended pattern for updateable function logic?
Thank you so much in advance.
