Can AI actually build a complex Avalonia UI? In this video, we put it to the test by taking a standard HTML Jobs Page mockup and forcing AI to convert it into a fully functional Avalonia XAML application.

While AI coding assistants are incredible at generating HTML, they often fall apart when it comes to specific C# UI frameworks. Today, we're diving into the reality of using AI to build a real-world Jobs Page in Avalonia UI. You'll see exactly where the AI struggles—from mangled grids and stack panels to broken data binding—and exactly how to fix it.
I'll show you my exact iterative process for "abusing" the AI into submission using screenshot feedback, prompt corrections, and manual XAML tweaks to get a pixel-perfect result.
In this video, you will learn:
• How to transition an HTML mockup into Avalonia XAML
• The specific layout and styling mistakes AI makes with Avalonia (and how to fix them)
• Setting up properly bound View Models with mock data
• How to effectively prompt AI for cross-platform .NET development
