It’s what I run on my home server. Most of my interaction with a command line is with macOS, which makes BSDs more familiar, and jails are nice for containment that works without external tools. First class built in ZFS is nice too.
I wonder if publishing for FreeBSD without one is problematic if you use either single-file JIT (trimmed, self-contained) executables or NAOT ones.
But given it's a server, such workloads generally favour JIT so it should not be an issue but I understand what you are getting at. With that said, it certainly doesn't seem to be as easy as `sudo apt-get install dotnet-sdk-8.0` but not as bad as building everything from source (which should not be too bad still, build.sh in dotnet/runtime does a lot of work for you to be able to just clone and build and the repo also has instructions for building for FreeBSD).
