Worked on the dotnet/SqlClient repository to address login timeout behavior by reverting the UseMinimumLoginTimeout default to true, ensuring that client applications experience consistent and predictable connection handling. This change preserved existing configurations while establishing a safer default, reducing variability in login timeouts. The approach included adding targeted regression tests to validate the new default and confirm that explicit settings remain unaffected. Leveraging skills in backend development, configuration management, and testing, and utilizing C#, the work focused on maintaining code quality and reliability. The update improved the stability of SqlClient’s connection logic without introducing new features during the period.
