NuGet Runtime pack for community-supported architectures

[driver1998]

Is your feature request related to a problem? Please describe.

.NET now has a few community-supported platforms: linux-riscv64, linux-loongarch64, etc.

And to properly support cross-publishing in .NET SDK, we need to get runtime packages from NuGet, otherwise publish will fail.

Hosting these packages on self-hosted repos are certainly an option, but is it possible now for maintainers to push those to NuGet.org under their own account? (Not as Microsoft because they won't be supported by Microsoft to begin with).

That way we can get a consistent publish experience.

Adding @richlander @MichaelSimons for a policy discussion around these other architectures.

This has been a problem for a long time. I think the gap here is a design.

I think this description captures the problem pretty well.

This also affects .NET on IBM platforms (eg, linux-ppc64le, linux-s390x)

AFAIK, the answer is currently no. The prefexes are reserved by Microsoft on nuget.org, and no one else can publish to the prefixes. Publishing under another prefix makes it non-trivial to consume, if it's possible at all.

[richlander]

Right. A design would need to enable publishing the various packs under arbitrary names and to provide a registration mechanism, likely via a NuGet package (or something equivalent).

Workaround:
A guide (Chinese only) to manually extract runtime packs from native SDK to your build SDK for cross-publishing scenarios (like from win-x64 to linux-loongarch64):
