Same thing for Qt Creator, although license may be an issue as always (although if it is then it's also probably not a problem, but I digress)

When I was a student, our teacher told us to just drag and drop GUI elements in Visual Studio and write the functionalities in C#. At that time I didn't knew that existed other ways to create user interfaces.

Winforms designer is pretty much it. But who's building windows apps these days :) ?

A looooooootttt of developers. https://www.hanselman.com/blog/dark-matter-developers-the-un...

I'm sure there's plenty of legacy apps out there that are getting maintained - but I seriously don't see anyone picking windows desktop as the only target for a new project these days.

Games, laboratory, healtcare and factory automation devices, kiosks.

Even automation stuff is moving to web interfaces and headless network connected controllers. Unless you're doing legacy stuff or niche stuff you're probably not writing stuff for windows desktop.

Game tooling has also moved to cross platform these days with popularity of MacOS for content creators and iOS as a target market requires MacOS for development tools.

Good luck with Web interfaces on air gaped devices.

Mac platform is about 15% of world desktop market, hope they can manage all requests from game studios all around the globe.
