Caliburn.Micro VS composePPT

It works with ActivateItemAsync but I don´t know if there is a difference that I should be aware of ? They seem to be a bit slow with updating the documentation so I´m a bit nervous about what else might not be updated yet.

The programming model reminds me of Rob Eisenberg's older attempts at building UI toolkits ([0]). I don't recall if that was fully async or 'just' using a coroutine/generator-style approach, but it feels similar.

I'm not sure the complexity of doing everything using async constructs is worth it, though. Large-scale UI's built in Qt or Javascript are mostly single threaded anyway, but it's still worthwhile to explore so kudos for that. Looking forward to seeing how far you get.

Vanilla WPF has a lot of boilerplate and verbose binding expressions. I'd check out an MVVM library like https://caliburnmicro.com/ which has tons of convention-based features and helps maintain the "screens" in your app.

Your UI needs to bind to something that can programmatically notify it about changes, we call these things View-Models. Usually View-Models implement INotifyPropertyChanged interface (another key interface is INotifyCollectionChanged that is responsible for notifying collection views that number of items is changed and they need to update the UI accordingly). You can do that (the implementation of the interface) manually or use some library to do that for you just to cut some boilerplate code (e.g. ReactiveUI + Fody or Microsoft.Toolkit.MVVM or maybe even this or this).

I haven't done WPF/XAML stuff in years but I really liked Caliburn Micro, largely because of the convention-based auto-binding.

Jetpack Compose (Google's alternative on Android, that also works pretty much anywhere you can run a JVM and others like the web [1], terminals[2], powerpoints[3], as well as pretty much anywhere you have an imperative API that you want to transform into a functional model[4]) is infinitely more polished and has better tools than anything Apple has put out in all of SwiftUI's existence. Apple is bringing this upon themselves with their "major updates" concept for SwiftUI coming every other year, where components aren't even available on old versions of iOS. A UI toolkit is a library like any other, version it like a library and match patch releases.

Today in "HN never used a reactive framework that is not React and is offended when UI is not written with Dear ImGui".

This is literally the exact style of SwiftUI and Jetpack Compose (down to the author having used the term fragment, I sure hope this isn't leftover trauma from being an Android developer), except written in Rust (hence having to deal with lifetimes in the middle, default parameters, lambdas being quite verbose and needing to move things, etc).

Not blocking the UI thread is mandatory if you ever want to make any kind of complex UI. If you're a web dev, well you only have one thread anyways, good luck, if you're on any other platform, interactions _cannot_ ever block the UI (unless you, yourself, update the UI to say it is blocked). Making this async is a good thing.

Stack traces are a problem, but then again they've been a problem in any remotely capable UI toolkit.

With ReactiveCell, it looks surprisingly similar to what Compose does, where modifying a State causes recomposition of everything observing it. Which means that it might be powerful enough one day to do the same things as Molecule (https://github.com/cashapp/molecule), or ComposePPT (https://github.com/fgiris/composePPT), where everything is a potential target and it interops really well with existing toolkits.
