MS discontinues a UI library project and then hypes up a new one every few years. Today Blazor and Maui are hot, but there's a lot of abandonware that came before.

You can see it in Windows too, where you can burrow deeper and deeper into progressively older settings dialogs, because they reshuffle the Control Panel every few years.

OTOH even stuff as old as Windows Forms (which literally shipped with .NET 1.0 - that's 2001!) still works and it actually has maintainers. You don't have to chase the shiny new stuff.

To be fair. Creating a good cross UI framework is hard. Winforms wouldn’t cross over to OS X / linux. WPF was too heavily tied to Windows. Silver light was a compeditor to flash and both of those died. Now we are up to Maui and Avalion? Blazor is more silverlight replacement imo.

Also, Winforms and WPF were designed before Microsoft embraced Linux and started making .NET truly cross-platform. Starting over with a new cross-platform UI framework sounds like a reasonable thing to do.
