Worked on enhancing the developer experience for porting to Microsoft.Data.SqlClient by updating documentation in the dotnet/SqlClient repository. Focused on the migration guide and porting cheat sheet, the work clarified backward-incompatible connection string changes and explained how SqlConnectionStringBuilder in Microsoft.Data.SqlClient introduces new aliases with spaces, which are unsupported in System.Data.SqlClient. Provided clear guidance for developers to sanitize connection strings by removing spaces from keywords, reducing migration friction and supporting safer transitions across library boundaries. The updates were implemented using Markdown and emphasized documentation skills, laying a foundation for more reliable and understandable porting processes in future migrations.
