> In my experience it does not work very well outside of the sanctioned Linux distributions. Quirky heisenbugs and nonsensical crashes made it virtually unusable for me on Void. I doubt that's changed in the years that have since passed.

It's open source. Did you follow the spirit of Linux to file a bug report of as much sense of the crashes as you could make? Most OSS only supports as many distros as people are willing to test and file accurate bug reports (and/or scratch the itch themselves and solve it). It seems a bit unfair to expect .NET to magically have a test matrix including every possible distro when almost nothing else does. (It's what keeps distro maintainers employed, testing other people's apps, too.)

It probably has gotten better since then, for what it is worth. .NET has gotten a lot of hardening on Linux and a lot of companies are relying on Linux servers for .NET apps now.

At the very least there are very tiny Alpine-based containers that run .NET considerably well and are very well tested, so Docker is always a strong option for .NET today no matter what Linux distro you want on the "bare metal" running Docker.
