Windows Forms is the answer you seek. It still receives updates to this day. I've been writing and shipping Windows Forms apps for 25 years. High DPI, dark mode, Edge web views, Blazor integration, we've got it all. Users don't even need to install .NET these days with self-contained deployment.

I will boldly claim Windows Forms is more stable than Gtk and Qt. Don't let random teams at Microsoft confuse you because they released yet another unrelated framework that you don't have to use. They are engineer-sirens trying to lure you from the true path. Let them pursue their promotions in peace while we rely on a stable workhorse.
