Worked on stabilizing the file-watching functionality in the Gum repository, focusing on robust error handling and file system operations using C#. Addressed a critical issue where the FileWatchManager could crash if no common root directory was found by introducing defensive null-checks in the root directory resolution logic. This approach ensured that edge cases were handled gracefully, reducing the risk of null reference exceptions and improving the reliability of automated file monitoring across projects. The work emphasized plugin development best practices, resulting in a more stable file watcher that minimizes downtime and enhances the overall resilience of Gum’s file-watching workflows.
