Waan contributed to the dotnet/vscode-csharp repository by engineering robust improvements to the C# debugging experience in Visual Studio Code. Over eight months, Waan upgraded debugger dependencies, introduced a COM wrapper for managed-to-native marshalling, and enhanced platform compatibility, particularly for macOS. Using TypeScript, C#, and JavaScript, Waan implemented guided prompts for asset generation, dynamic debug configurations, and maintained alignment with evolving Visual Studio releases. The work included targeted bug fixes, dependency management, and careful rollbacks to preserve stability. Waan’s approach emphasized cross-platform reliability, maintainability, and clear user messaging, demonstrating depth in backend development, extension architecture, and version control practices.
March 2026: Focused on stabilizing the .NET Core debugging experience in dotnet/vscode-csharp by updating the debugger URLs and integrity hashes to version 2.131.0 across Windows, macOS, and Linux. This release ensures the debugger functions correctly across all supported environments and reduces user-facing issues. The change was implemented via commit 419c4d6947dc38cc3d78d74729328ea2ebbcf4d0 (Update debugger for v2.131.0 (#9043)) and validated through internal testing and cross-platform checks.

In November 2025, the focus was stabilizing the debugging experience in dotnet/vscode-csharp by rolling back the debugger from v2.95.0 to v2.90.0 due to issues observed with the newer version. This targeted rollback preserves established debugging workflows and minimizes risk while maintaining alignment with the repository’s baseline tooling. The change is captured with a single revert commit and full traceability.

April 2025 — Focused on stabilizing and accelerating the C# debugging experience in the VS Code C# extension. Implemented Debugger improvements targeting version 2.72.0, addressing reliability issues such as the 'Evaluation timed out' bug in the Debug Console, adding a progress dialog for long-running evaluations, and optimizing IL interpreter performance. Also updated Mono debugger and aligned with Visual Studio 17.14 compatibility. These changes reduce debugging friction, shorten iteration cycles for .NET developers, and improve overall extension performance.
