There are also legacy images of Mono 4.8, 5.0, and 5.4 based on glibc hack:
$ echo 'using System; class MainClass { public static void Main (string[] args) { Console.WriteLine ("Hello World"); } }' > qq.mono
$ docker run --rm -v "$(pwd)":/mnt frolvlad/alpine-mono sh -c "mcs -out:/mnt/qq.exe /mnt/qq.mono && mono /mnt/qq.exe"
Once you have run these commands you will have qq.exe
mono-executable in your
current directory, and you will get printed 'Hello World' from Mono!
