Same. WPF in an MVVM pattern is so comfortable to use once it clicks. It has its quirks but for everything there is a workaround once you stick to the pattern.

For the creators of Mahapps I have eternal gratitude.

Windows has multiple competing standards in the same OS, even from their own software distributed with the OS. It’s embarrassing.

WPF has no such concept. Even if you don’t use a library for this, it’ll then just use the built in style after detecting your OS version and adapting to that. But it does this by pulling out hard coded resources shipping with WPF. If you wish, you can override and tell WPF to look like XP on Windows 10 instead… It’s all just a good try, but still a facade. It does not and can not (per design) rely on “native controls”. I suppose because it’s DirectX based rather than GDI.
