SUMMARY Pretty much the only editors that support XAML live previews (that are still active) are Visual Studio and JetBrains' Rider... both of which are proprietary editors. With Rider having the additional beef with requiring a license under certain conditions. There's https://github.com/VitalElement/AvalonStudio , but that project hasn't had a commit for 2 years and issues are piling there. There's also this Avalonia VS Code Plugin... https://marketplace.visualstudio.com/items?itemName=AvaloniaTeam.vscode-avalonia But that's VS Code, and I moved away from there because I wanted to use KDE technologies as much as I can. STEPS TO REPRODUCE 1. Install Kate 2. Install OmniSharp language server 3. Start a XAML project 4. Enable the language server OBSERVED RESULT No XAML preview support exists DESIRED RESULT For XAML preview support to exist SOFTWARE/OS VERSIONS Linux: Gentoo (LLVM) KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.12
I think a XAML preview implementation is out of scope. If somebody provides a plugin or an LSP server that somehow does that, it is fine, but I don't see that we as a team will work on that.
