Pull Request Overview
This PR improves error reporting in the XAML Source Generator (XSG) by adding diagnostic reporting when content cannot be added to an element that lacks a ContentPropertyAttribute. The change aligns the source generator's error handling with the existing build tasks behavior.
Key Changes
- Enhanced error diagnostics in the source generator to report when content cannot be set on elements without ContentPropertyAttribute
- Updated unit tests to verify the new diagnostic reporting functionality
- Cleaned up commented code and preprocessor directives

The method LocationCreate is being called but it's not defined in this class or imported. This will cause a compilation error.
