Worked on the dotnet/project-system repository to enhance accessibility and extensibility within the Visual Studio Project System. Addressed a launch.json UI issue by adjusting access modifiers in the Query.PropertyPages namespace, enabling external access and ensuring proper UI functionality. Developed a new public API surface for project querying, state management, configurations, and rule data, laying the groundwork for improved project introspection and future tooling integration. Applied skills in API design, C#, and IDE integration to deliver targeted, incremental improvements that align with code quality and API governance standards, supporting both immediate usability and long-term extensibility for external developers and tools.
