Worked on stabilization and maintenance of the PowerToys repository, focusing on solution file management and merge conflict resolution using C#. Addressed a critical issue by removing a duplicate WorkspacesCsharpLibrary entry from the solution file, which resolved a merge conflict and restored correct solution configuration. This fix reduced build failures and improved the reliability of continuous integration processes. The approach involved validating the solution structure, documenting changes, and ensuring future merges would not introduce similar duplicates. No new features were delivered during this period, with efforts concentrated on codebase hygiene and maintaining a stable development environment for onboarding and ongoing development.
