Unhandled exception: An error occurred trying to start process 'bash' with working directory '/app'. No such file or directory

Describe the bug I am trying to get Terminal.GUI based app to run on docker. Host is Ubuntu 20.04 under WSL, and target is Alpine Linux. I get error about bash, which I assume is not required with Alpine Linux.

The error is:

Unhandled exception. System.ComponentModel.Win32Exception (2): An error occurred trying to start process 'bash' with working directory '/app'. No such file or directory

Thank you very much.

If you mean the reproduction steps, they are the same as in my first post (the repo has been updated with newer .csproj file).
