saying OOP is only useless and counter productive is as short sighted as saying it is the golden hammer for everything.

PS: WinUI apps use plenty OOP

[_old_dude_]

It's not what i've said, OOP is great for creating APIs like WinUI, not great for writing applications

[jcelerier]

In which universe an application which uses mainly OOP APIs isn't itself OO.

[_old_dude_]

What OOP is good at is maintenance over the time by making clear what is API and what is implementation.

My point is that when you develop an application, you only need strawman OOP i.e. calling methods.

You don't need class inheritance if you can pass functions as parameters, you don't need encapsulation given all your pieces co-evolve at the same time (if it's not split than part into a library).

and WinUI apps are applications, and - as said - OOP is used by them, see e.g. the reference architecture guide
