To be honest, Maui evolves xamarin.forms and winui3 is an evolves from winui, uwp and winrt. That kills half of the entries. Maui/xamforms is not a ui toolkit but an abstraction... So plays in a different league (with e.g. react native for windows which is also maintained by microsoft). Silverlight and wpf are the original sin here and born in and hyped by the dev division in a time where the Windows division was busy fixing XP and failing on Longhorn. I would add that the webview2 (since html is definitely a ui toolkit on its own). And when you add Maui then you may also add Blazor.
