Hah, WinForms is still my go-to for quick Windows GUIs. Perhaps is WPF used CSS instead of god awful XML boilerplate overrides for styling I might use that.
Same here! Hard to match WinForms productivity for small apps, especially if you cut your teeth in the 90's VB era. And you can push WinForms really far with the fancy controls in the Syncfusion Community License.
Winforms is absolubtely my go-to as well after using it briefly at work for a project around 2015. It was old then, but I really liked the way it worked, it was sensible and c# is always easy compared to c++
