XAML.io adds “Migrate from WPF”: run an existing WPF application on the web
Userware released XAML.io v0.8, adding a 'Migrate from WPF' feature that lets developers bring existing Windows Presentation Foundation apps to the web without a rewrite. Powered by OpenSilver, the tooling compiles C# and XAML to WebAssembly and renders the UI as real HTML DOM elements. A free Compatibility Analyzer scans compiled WPF apps and reports what works, what needs adaptation, and what is blocking. Rather than regenerating code with AI, the approach preserves original source files and applies minimal, reviewable changes. A migration of the Family.Show reference app demonstrated 97% of code unchanged. The self-serve tools are free; Userware also offers professional migration services for larger enterprise codebases.
