I once was in charge of a legacy C codebase that passed around data files, including to customers all around the world. The “file format” was nothing more than a memory dump of the C data structures. Oh, and the customers were running this software on various architectures (x86, sparc - big endian, alpha, itanium) and these data files had to all be compatible.

Occasionally, we had to create new programs that would do various things and sit in the middle of this workflow - read the data files, write out new ones that the customers could use with no change to their installed software. Because the big bosses could never make up their minds, we at various times used C#, Go, Python, and even C.

They all work just fine in a production environment. Seriously, it’s fine to choose any of them. But C# stands out as having the ugliest and sketchiest code to deal with it. But it works just fine!

More telling though. I used this scenario in interview questions many times. How would you approach it with C#? 99% of the time I would get a blank stare, followed by “I don’t think it’s possible”. If you want developers that can maintain code that can do this, perhaps don’t choose C# :)
