But that doesn't describe what we are paid to do. I regularly have to ensure solutions work in both OS X and in Docker / Debian. If the question was: "Which operating systems does your company target" the answer is both Debian and OS X. Because most developers work in OS X and our production machines run Debian.
What if i run some remote development tools like gh codespaces or the like?
Whatever operating system your thin client runs.
I’ve always answered that I use both Linux and Mac (recently I had to add windows as well) as I write on a Mac and run it on Linux. Regardless you shouldn’t just answer it as whatever your thin client is running as then the WSL option doesn’t make sense.
