Avalonia.FuncUI VS WPF

For those interested in .NET languages with alternative compilation targets, Elmish (https://elmish.github.io/elmish/) is pretty unique.

We use F# on the front end (instead of TS), and thanks to the Fable compiler (which transpiles F# to JS, Python, Dart, PHP and Rust), most of the benefits of an Elm-style model in the UI can be ported to all sorts of different outputs languages. The rust target is in beta, but its promising because the WASM bundle size stands to be dramatically lower.

While the default is reactivity library for Elmish is React, you can swap in Avalonia/FuncUI (https://github.com/fsprojects/Avalonia.FuncUI) pretty easily as well.

The code to declare/build the widgets is quite nice. Modifying widgets by hand on certain signals or manually re-wiring all the signals seems a bit outdated to me.

Wonder if something like FuncUI [1] could be built on top of it.

OTOH, if desktop really is the primary focus, and if you can drop the idea of reusable UI code, then Avalonia is a great choice for F# as you can use a Avalonia.FuncUI and/or Elmish.Avalonia.

You might want to check out Avalonia.FuncUI, which lets you use F# and the cross-platform Avalonia framework to build desktop applications with an Elm-like architecture: https://github.com/fsprojects/Avalonia.FuncUI#example-using-...

Gear up, folks, and test drive this fresh-off-the-lab feature. And should you stumble upon any glitches along the way, don’t hesitate to reach out. Got a bug to report or feedback to give? Send them directly to our dotnet/wpf repository. We’re eager to hear from you, because together, we’re only going to make the experience even better!

I did some research and did not find any proof of the EOL on WPF. In fact, Microsoft just updated the roadmap on WPF 2 months ago.

There’s still room for improvement though. I should add, WPF on .NET Core consumes a lot of memory, due to a memory leak. It was logged by our COO as one of our users was doing a comparison.

have you tried this?

WPF: Licencia MIT.

Some added context: It's a side effect of how variable rendering works in UI library we use. There's currently sadly no way how to disable VRR compatibility, which causes the issue you describe unless you tell your GPU to not treat Playnite as VRR compatible. Some more info here.

WPF is definitely not dead. It may not be the latest shiny thing, but it works, it is maintained (judging by https://github.com/dotnet/wpf or https://devblogs.microsoft.com/dotnet/wpf-on-dotnet-7/), and it is fully and officially supported on the modern .NET platform.

This article only sights a video stream. I think part of the problem with the glacial pace of development is reliance on manual testing. See this comment:

> Our primary goal is to ensure reduced turn-around-times for new PRs as well as clear the pending backlog of existing PRs. To that end, we are working on putting appropriate automation in place to reduce the dependency on manual testing as much as we can.

If you look at the history of this file you can over the years tests have been always been in the backlog.

As for “where projects go to die”, they have 3 features planned for this year: Windows 11 Theming, a new type of folder browser, and null ability annotations. And they say they don’t think they can do them all. Maybe I’m underestimating, but that’s not a lot.
