Multifile assemblies on non-Windows OSes

[sotlef]

It is hard for me to guess right project to address this issue, sorry if I misaddress it

Is it possible to create crossplatform multifile assembly according to documentation: Build a Multifile Assembly

I mean possibility to:

• compile C++/CLI files to .netmodule on Windows (as I know there is no C++/CLI compiler on non-Windows OSes)
• compile C++ to native object files on linux for instance with gcc
• compile C# code to .netmodule
• link them all to one assembly with al with reference to netstandard or netcore frameworks?

I'd say that this probably belongs on either CoreCLR if the question is around the runtime support/behavior of such an assembly, or on Roslyn if the question is around the tooling of building such an assembly.
