Worked on enhancing the development diagnostics experience in the dotnet/aspnetcore repository by implementing a targeted feature for the Developer Exception Page. This involved updating the DeveloperExceptionPageMiddleware to populate the IExceptionHandlerFeature, providing developers with richer exception context during the development process. Using C# and leveraging skills in ASP.NET Core and backend development, the work focused on improving the clarity and usefulness of exception information available during debugging. The enhancement enables faster identification and resolution of issues in development environments, supporting higher-quality development cycles. Unit testing was applied to ensure reliability and maintainability of the new diagnostics functionality.
