Worked on the dotnet/SqlClient repository to enhance localization resource management by consolidating the NeutralLanguage setting into AssemblyInfo.props and removing the explicit NeutralResourcesLanguage attribute from Microsoft.Data.SqlClient.cs. This technical refactor, implemented using C# and MSBuild, reduced configuration drift and improved the consistency of resource language handling across the project. The approach centralized localization settings, making future updates and automation more straightforward while maintaining compatibility with all supported cultures. By focusing on build configuration and resource management, the work lowered the risk of locale mismatches and simplified both localization debugging and multi-language support for downstream users.
