Top 23 C# GUI Projects

Avalonia
Develop Desktop, Embedded, Mobile and WebAssembly apps with C# and XAML. The most popular .NET UI client technology
Check out https://avaloniaui.net as well. It's basically a cross-platform reimplementation of WPF. It's not quite as simple as C#+WinForms or Lazarus+LCL because you don't get drag-and-drop UI designer, and you need to write markup by hand (albeit with live preview). But unlike HTML, it's actually designed for desktop UI apps from the get go, so it's much easier to write for anything non-trivial. And you can still write "quick and dirty" GUI code by directly connecting event handlers to buttons and updating values etc in it, ignoring data bindings and other more advanced facilities.

I was going to complain how Avalonia still has issues with large binaries even with NAOT but I just tested it on https://github.com/sourcegit-scm/sourcegit, and the resulting size of the folder without symbols (so, the binary itself and like 4 dlls) is ~55MiB. The binary itself is 41MiB which is as much as Qt6-based qBitorrent binary takes on Windows. So it seems while Avalonia works well enough on macOS, the size of binaries and memory consumption are higher than on Linux and Windows huh.
