Winforms? lol at them still bekng the best option. so much wasted effort trying to replace them
Winforms is great until you try to make windows dynamically sized, or deal with DPI nicely. In every other regard it's still fine, and for accessibility actually _better_ than many subsequent frameworks. And produces nice small fast executables.
Winforms is also .NET based, so it's inaccessible if you don't want to write your UI in and take a dependency on .NET.
