During January 2025, Hadhaliw worked on the dotnet/project-system repository, focusing on improving project action scoping within Visual Studio. They addressed a bug where launch profile and property page actions were incorrectly processed for non-.NET projects by introducing the AppliesTo attribute with ProjectCapability.DotNet to both LaunchProfileActionProvider and ProjectActionProvider. This change, implemented in C# and leveraging attribute programming and API design skills, ensured that these actions now execute only within .NET project types. The update improved reliability and user experience in multi-project solutions by preventing unintended UI behavior, demonstrating a targeted and thoughtful approach to project system development.
