Not the most pressing issue -- is there a reason Linux repositories are x86_64 only? This has been the case for past releases, but there was talk that it could change for 6:
dotnet/runtime#3298
(also dotnet/runtime#3263 but doesn't mention 6.0 timeframe).

Great question/topic @lmcdougald. We are working on adding additional repositories (Arm64, Alpine, and previews). Thanks for raising this. The feedback legitimately helps.

@lmcdougald the work add additional packages for Arm64 is tracked with this .NET 6 issue: #5446

Where do I go to find out more about .NET 6 and Windows Store Apps?

[rgwood]

@mandalorianbob Depends on what exactly you're interested in, but you may wish to check the WinUI roadmap and this Project Reunion thread. As of this time, I believe there is no public ETA for being able to run UWP apps in .NET 5 or 6.

[mandalorianbob]

Yeah I'm interested in being able to run UWP apps in .NET 6, so I guess that answers the question haha. I'm also posting inquiries to Project Reunion.

On the subject of .NET 6, I think it might be a good idea to take a look at this for possible implementation. Should be relatively effortless of an upgrade: https://github.com/thpatch/win32_utf8

Additionally, I'd look into adding native support for things like Large Memory Pages, Ravioli Memory, and OpenACC/OpenMP. This way, people migrating to .NET 6 would get these features right out of the box!

[lukemcdo]

Unless I’m mistaken the feature window probably won’t be expanding much at this stage. Also, .NET 6 is supposed to be a clean recompile from .NET 5 supposedly (unless that promise is dead) so I’d expect the UTF8 change to be a non-starter as well.

[Amaroq-Clearwater]

I was more referring to the fact that it's a drop-in replacement for stdio.h / windows.h, which transparently turns ANSI and UTF-16 Win32 functions into UTF-8 versions... and as an added bonus, also helps troubleshoot various compatibility issues by giving you error messages that are actually helpful.

Also, because you're just importing a library, and swapping a couple of include lines... It really is a pretty trivial thing, IMHO.

Closing in favor of #6057
