I've worked with C# off and on for over a decade, and never encountered anything close to that. Maybe the trick was that I was working with competent people.

Now the Fortran code I've encountered, that's the stuff of nightmares (to be fair to Fortran I've also encountered good code, but there seems to be a generation of embedded developers who have no formal programming training that all adopted a style of Fortran inspired by Cthulhu).
