MAUI is not ready. I started a Greenfield project this year. Having tried a serious project in Xamarin Forms, I reached for WPF. The app is almost ready and the speed at which I was able to get stuff working (and beautifully so) has resulted in our company being able to win new business. WPF has no limits. It just works. Tons of community support.
My hope is that MAUI gets to WPF level soon. Refactoring away from WPF to MAUI should be almost trivial, if desired.
Okay - this is not going to happen. WPF lets you do really complicated binding tricks that XF was just not capable of. Maui is just an evolution of XF, but so far I think iit is a step back from what we had before. We have some stuff working, but it was painful to make it work and some of the WPF tricks we used in XF with binding are broken in Maui so far. I'm sure we will fix most of them, but it feels like we will just refactor a lot of it away to simple properties rather than complicated multitrigger bindings. I echo "Maui is not ready".
