WPF VS Windows UI Library

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.

I wish that was true, but even the new stuff, like their new frameworks, performs poorly while their older frameworks perform really well. That's brand new code, with no legacy codebase to care for.

The reason why I don't recommend Winui is the million bugs it has. See the github issues page. All Microsoft ui stuff sucks currently. But if you use WPF why not FluentWPF

Development for WinAppSdk and WinUI 3 is also very slow and Microsoft seems to not want to push it and invest more developers into it for some reason. They try to improve the framework, is just it's a small team. For example it was a headacke to apply the Mica backgrop and required unmanaged code, they made it simpler and reduced it to a line of code but it took months. I have 2 out of 7 issues fixed on WinAppSdk repository and 0 out of 8 issues fixed in the WinUI 3 repository (some of the older than a year). This are just my issues, there are many other opened by other developers. So yeah, it wasn't fun at all. PoweshellSDK had an issue with the Import-Module command and it wasn't fixed for more than a year and probably won't be ever fixed, but I'm glad I found a workaround, even more clean and more safe, otherwise I couldn't have added the posibility to uninstall and change Store apps.

Compared to UWP or WPF, WinUI 3 is somewhere between 100-200% slower and consumes 7-20 times as much RAM as the old frameworks (for certain operations).
