This is some code that I’ve used as a fun way to teach C# threading concepts with a limited time budget. It works best in small groups, where people work together to figure out differences between implementations and then afterwards analyze the sources.
I am working as a software developer and speak English, Danish (both non-native) and German on the job. I do not recognize the problem you describe at all. If there is confusion, it usually stems from the classics: missing or unclear requirements, bad or non-existent communication, implicit assumptions about what everyone should know and so on.
