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.

Introducing .NET Multi-platform App UI (MAUI)
.NET MAUI is the .NET Multi-platform App UI, a framework for building native device applications spanning mobile, tablet, and desktop.
Project mention: .NET MAUI Authentication on Windows: The OpenID Connect Challenge | dev.to | 2025-05-06You know, I'm not the only one surprised by this issue. If you take a look at the long threads around this issue, you can see many developers are complaining about the missing support for a very common feature such as authentication in Microsoft's own operating system!

Project mention: The Windows Subsystem for Linux is now open source | news.ycombinator.com | 2025-05-19
> whereas Microsoft is actively sabotaging wine
Do you have a link to where I can read more about this? My understanding is that Microsoft saw Wine as inconsequential to their business, even offloading the Mono runtime to them [1] when they dropped support for it.

Uno Platform
Open-source platform for building cross-platform native Mobile, Web, Desktop and Embedded apps quickly. Create rich, C#/XAML, single-codebase apps from any IDE. Hot Reload included! 90m+ NuGet Downloads!!
As-is today, AI tools provide some productivity gains. However, they are not replacements for experienced developers. At Uno Platform we are investing in tools which make developers productive within their current environments, such as Hot Design. Also, we are keeping a close eye and thinking of these useful scenarios to apply AI to, as we don’t believe just adding a simple LLM to it will actually add value. So, stay tuned to our blogs and Dev.to account as there is more goodness coming on this topic.
