Online XAML Editor

The tool edits XAML in-browser with flavor-aware validation and diagnostics. It parses XAML into an intermediate representation and reports syntax errors, missing namespaces, and flavor-compatibility issues. It supports WPF, UWP, Xamarin.Forms, and MAUI flavors, surfacing anatomy of markup and potential cross-flavor adjustments. It does not execute code; it focuses on structural correctness and refactor opportunities.

How it works conceptually: provided XAML is parsed, analyzed against the selected flavor, and transformed into an editable representation. A lightweight AST supports validation, namespace normalization, and change proposals. Diagnostics include line/column location and severity to guide fixes; formatted output can be generated for easy integration into source control. The tool also supports fragment export for reuse in other projects.

Who benefits: developers prototyping UI, engineers migrating UI between .NET flavors, educators teaching markup, and teams performing code reviews. Unique value arises from browser-based access, cross-flavor validation, and actionable recommendations without requiring a desktop IDE. Core features include syntax validation, namespace checks, flavor-aware rules, and fragment export. Common use cases include quick edits during design reviews, learning XAML syntax, and preparing snippets for documentation or tooling pipelines.
