Not really true any more! I've done most of my development in Windows, true, but my understanding is that development on Linux is pretty much a first-class citizen these days.

You can definitely deploy/host the application on Linux just fine - we do it all the time!

And how does it work now? I remember I tried it in the old days, but noticed serious memory leaks after 30 days or so, so I decided to periodically restart the server to avoid them as debugging this stuff was a real PITA.

.NET 6 runs on Linux without issues (for web applications, it's mostly GUI applications where there are still major differences between platforms).

Run what? You can run it on Linux and Macos:

No, you don't. I work for an enterprise software company that built on .NET for 20 years. We just upgraded the codebase to .NET 5, and all future deployments will be on Linux.

Wow. This is more than half a decade old joke.
