During March 2026, Hextaku contributed to the dotnet/sdk repository by developing targeted formatting capabilities and stabilizing restore workflows. They introduced a framework-scoped formatting option to dotnet format, allowing developers to restrict formatting to specific target frameworks for improved flexibility and performance. Using C# and the dotnet SDK, Hextaku also resolved restore-time failures by removing unsupported arguments from the restore path, ensuring reliable project restoration. Their work included internal code refactoring, standardizing method signatures and localization patterns to enhance maintainability. The depth of these changes reduced future regression risk and improved consistency across restore and formatting surfaces within the codebase.
