If you have a Windows server and you're writing .NET code the only option (of you want the latest .NET version) is to use Windows workstations. That's like saying OSX runs great on Macbooks. It is designed to do that.

I'm saying Windows Server ties in nicely with the desktop versions of Windows (managing permissions and accounts, AD, email, network resources etc). Its like saying OSX server works great with Macbooks.

And my point was perhaps the reason people are using Windows server is not because Linux is too hard and unfamiliar but because just maybe it's a better fit.

I think your missing the point. "It just works" is a huge selling point.

At best you can "it just works if you already know it well"; having done Windows development at three separate jobs, I still find it fiddly to get a dev environment working on Windows.

If everything in the MS ecosystem "just works" then I am either willfully overlooking its great features or like so much else, it's a function of what you know best.

There's little to gain by switching to another OS if you have enough money for licenses and you know its ecosystem well.
