Yep, it also works fairly well. I'm maintaining a couple services at my day job that are designed to only work on Linux. VS Code is also involved because we're heavily using the Remote Development feature (which only works in MSFT's VS Code, not in VSCodium, because of licensing) to run the IDE core inside the container, so the dev environment is well standardized and portable across devs/host OS

.NET core works pretty well on Linux - I have an ASP.NET Core side project and work exclusively from a Linux machine. The other two maintainers work from Macs.
