Month 2025-10: Delivered a foundational feature improvement in microsoft/agent-framework by refactoring the application shutdown mechanism to use IApplicationLifetime instead of a custom CancellationTokenSource in the Agent_Step09_DependencyInjection sample. This aligns with standard .NET hosted service patterns, reducing complexity in dependency injection and enhancing shutdown reliability. The change is associated with commit 43fe7c6dbea0d63c4a6e3affe39a4e5caec870ba ('Use IApplicationLifetime instead of a custom token (#1031)'). Impact includes improved stability during startup/shutdown, easier maintenance, and better readiness for future lifecycle enhancements. Demonstrated skills: .NET hosted services, IApplicationLifetime, Dependency Injection, code modernization, and strong commit-level traceability.
