I was talking about .NET's publish modes (NativeAOT, portable assembly, etc.). You are also confusing what it means to produce a portable assembly with the ability to target across operating systems or CPU architectures. (also, most native toolchains do not let you easily cross-compile, Go makes significant sacrifices to make it possible, as long as you have no dependencies which rely on C/C++, and there are many of those)
