Pull Request Overview
This PR fixes XML namespace (xmlns) resolution issues when compiling XAML with the source generator, specifically for visual state targets. The fix ensures that type resolution considers the correct namespace context when resolving types in visual state setters.
- Updates the BindablePropertyConverter to properly handle XmlType objects instead of string type names
- Modifies NodeSGExtensions to use XmlType for type resolution in source generation context
- Adds comprehensive test coverage for the xmlns resolution scenario
