Is the fact that C# produced executables also a problem? With python you can ‘protect’ non lab computers at the school by just not installing the python runtime on them. Teach them c# and I guarantee they will be making executables to cause trouble.
Generally agree with you that teachers should be able to choose at least one of the languages to teach. basic web dev stuff is probably pretty useful to them though if it includes JavaScript?
Oh, ok, that’s annoying then. One of those cases where it feels like the person putting the course together has never actually interacted with children?
