You're also very kind, and I realized that it's possible there were a bazillion "watch out"s on the docs and was just trying the <PublishAot>true trick when I s

  You need an OS for which you are building to be able to compile an AOT binary - it depends on OS-provided tooling (MSVC on Windows, Clang on macOS and Linux, and a system-provided linker from each respective system). In fact, once ILC is done compiling IL to .a or .lib, the native linker will just link together the csharp static lib, a GC, then runtime/PAL/misc and a couple of system dependencies into a final executable (you can also make a native library with this). Cross-architecture compilation is, however, supported (but requires the same extra dependencies as e.g. Rust). If you just want to publish for every target from a single docker container (you can't easily do that with e.g. Rust as noted), then you can go with JIT+single-file using the other command. Keep in mind that Go makes concessions in order for cross-compile to work, and invested extra engineering effort in that, while .NET makes emitting "canonical" native binaries using specific system environment a priority and also cares a lot about JIT instead (there aren't that many people working on .NET compiler infrastructure, so it effectively punches above its weight bypassing Go and Java and matching C++ if optimized).
