ModernWpf

This one looks pretty solid. There are loads of them. The demos I’ve seen all showcase live feedback. https://superguigui.github.io/simple-color-picker/ Compare to the best I can find for WPF: https://github.com/dsafa/wpf-color-picker - no live feedback, dialog only, no documented support for modern .NET. There are some commercial controls available from syncfusion and the like if you want to pay for such things. Compare to color dialog in WinForms: https://github.com/Kinnara/ModernWpf/issues/72 WinUI has a decent color picker, but there are other trade offs going with WinUI that make it inferior to the web environment (e.g. broken rendering of SVG/paths).

Neither WPF nor WinUI are using OS controls for most of their GUI. Their GUI is defined by styles and templates in various XAML files. You can make controls look however you like. Microsoft did a great job back then re-implementing UX of WinXP and Win7 on top of WPF, but unfortunately not the newer Windows versions. Here’s a third-party project with styles and templates implementing GUI similar to Win10: https://github.com/Kinnara/ModernWpf Their approach seems correct, and the screenshots looking nice. I never needed that library BTW, my clients who need good GUI usually provide professionally-made design which is unrelated to Windows controls. Also, here’s a relevant GitHub issue https://github.com/dotnet/wpf/issues/5793 which currently says “.NET 7.0 milestone”, however the 7.0 is scheduled for November 2022, i.e. in about 1 year, and

Pretty slick. A mc on steroid for a GUI world. Interesting that it was built in .Net and appears to be using WPF with a few improvements[1]. It also refers to Vanara[2] which looks interesting as a safe utility wrapper to the Windows API. [1]:https://github.com/Kinnara/ModernWpf [2]:https://github.com/dahall/Vanara
