February 2026 performance for dotnet/SqlClient focused on enhancing reliability through standardized error handling. Delivered a feature to expose a default transient SQL error list for retry logic providers, enabling applications to reference a baseline of common transient errors and improve the reliability of SQL operations. This baseline reduces ad-hoc error handling and supports consistent retry policies across consumers. No major bugs fixed in this period for this repository. Business impact includes more robust database interactions, easier maintenance of retry configurations, and potential reductions in support costs. Technologies demonstrated include .NET, C#, SqlClient, and error-handling patterns used to standardize resilience across the library.
