Sep 1, 20252025-09 monthly performance summary for microsoft/vscode-mssql: Security, performance, and maintainability enhancements across the extension. Delivered cross-OS credential store integration to strengthen authentication and streamline onboarding, and introduced a parallel processing launch option for STS to improve query throughput. Architectural improvements included moving all document connection handling out of the main controller and consolidating Query Creation and Connection Management to reduce complexity and improve testability. UI/UX updates included migrating the grid context menu to React, adding a scrollbar to the user survey page, and enabling shift+arrow selection in the results grid, significantly improving data exploration and feedback loops. Data capabilities were enhanced with ResultGrid contextualization and HybridDataProvider filtering/sorting, along with summary loading progress indicators to improve perceived responsiveness. Additionally, a broad set of reliability fixes was completed: consolidated connection error handling, null checks for OE service initialization, and a series of bug fixes across tools (toolbar icon, webview panel creation, invalid URIs, tests Windows EOL, auto column sizing, and more). The combination of these changes reduces time-to-value for users, increases system stability, and lowers maintenance costs by clarifying code paths and strengthening test coverage. These efforts demonstrate proficiency in security engineering, UI/UX modernization with React, data-layer enhancements, and robust error handling at scale.
