Worked on the MaterialDesignInXAML/MaterialDesignInXamlToolkit repository to enhance the reliability of XAML converters within the hint system. Focused on stabilizing converter behavior by addressing a type safety issue in the FloatingHintInitialHorizontalOffsetConverter, ensuring it consistently returns a double value rather than an integer. This change eliminated XAML runtime errors caused by implicit type conversions, improving the robustness of the UI component. Utilized C# and WPF, with particular attention to XAML converter implementation and runtime type consistency. The work prioritized bug resolution and code stability, reflecting a careful approach to maintaining compatibility and preventing subtle runtime issues in WPF applications.
