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.
