WinUI, The modern native UI platform of Windows
I have to work with WPF on a daily basis. What a nightmare, and how I miss working with Qt. I wish the people responsible for WPF were forced to use it for the rest of their lives.
The grid layout is broken. The stackpanel is broken. There are no sane defaults for anything. You can rotate any control - WHY? Default stackpanel has no control spacing. WPF code throws no exceptions. Bound comboboxes in datagrids have the performance of glaciers. Keyboard shortcuts trigger the decades-old &#x27;edit field contents only transfer on killfocus&#x27; bug. Parent-windows and always-on-top is a mess.
Live dom is different from your static hierarchy.
  I&#x27;ve waited for fixes to the WPF mess since.. 2007?
I sense WinUI isn&#x27;t it.
