Your second paragraph sounds like you're describing Avalonia. Avalonia has AOT, compile-time binding errors and cross-platform support. Maybe there have been some updates since you last tried it? I'm not very familiar with Avalonia or WPF though so maybe there's more to it than that.

Thanks, yes I'll probably have to give it another try some day. I might be confusing Avalonia and Uno, but I think I first attempted it a couple years ago, and then again last year. I remember spending a whole weekend trying to get it running but wasn't having success. Also, I was a bit turned off by how heavy the development environment was. I had to download and install a tool, then that installed more build tools and packages, and then there was also a "recommended" VS Code extension. With WPF, I've gotten used to writing XAML without a designer, so I can get by with just VSCode, the C# extension, and the .NET CLI.
