Would a Declarative Reactive UI be too expensive?

Most of them are 1:1 with System.Reactive though there are some new operators, too.

Well, once each input stream has pushed at least one item.

And you'll see it emits a new item (containing the latest value of each input) each time one of the input streams pushes a new item.

Like if you don't understand what CombineLatest does, you can always look at https://github.com/Cysharp/R3/blob/main/tests/R3.Tests/OperatorTests/CombineLatestTest.cs

The unit tests seem really clean and concise. Which helps understanding how certain features work.

Yeah, observables are awkward. I need to invest time into R3 basics at some point. Largely same thing, but different implementation. https://github.com/Cysharp/R3

I assume the pattern can be smarter with pooling (and the limitations that would come from that) and make MVU reasonable with said enforced pattern. But that's a lot of invested time. Time that I prefer the pattern architect to put in, not me.

Not entirely related, but Avalonia allows you to bind directly to observables. Though it's still a one-way road.

Uno has its own adaptation called MVUX: https://platform.uno/docs/articles/external/uno.extensions/doc/Overview/Mvux/Overview.html?tabs=viewmodel%2Cmodel

No idea. I saw the pattern and I'm not willing to put real time behind unproven stuff in .NET, especially if it has obvious flaws (object churn).

In case you need inspiration. I still personally just don't like it. 🤷‍♂️

Well, the Avalonia PropertyStore (system which manages bindings, setter priorities, etc) is built around observables. So you can do a lot with reactive programming.

Of course, other XAML frameworks aren't implemented as native, so you only get part of those benefits.

So if you're using UWP (or presumably WinUI3), then there are a lot of perf improvements you're losing by moving your UI into C#.
