It can be an issue in C#. I've seen some mad circular dependencies between files. The file hierarchy doesn't always reflect the namespace hierarchy which sometimes doesn't reflect the actual code dependencies hardly at all and untangling the messes that result from that can be a big deal. I'm not sure a project gets into that state "real quick", but it remains something that projects can do over time, sometimes without realizing it, especially when a DI abstraction makes it even less obvious how circular a project's dependencies really are.
