Nov 1, 2024November 2024 monthly summary for dotnet/sdk: Across testing, build efficiency, and extensibility, the team delivered concrete changes with measurable business value. Key features delivered include an extensibility hook in the .NET SDK props (post-import hook) to support additional default processing or custom build configurations. Major bugs fixed include: 1) Mock Workload Resolver updated to 8.0.100 to align tests with workload set 8.0.302, ensuring test expectations reflect correct versions; 2) Avoided unnecessary Windows SDK reference pack downloads for C++ projects, reducing build times and resource usage. Overall impact: improved test reliability, faster CI builds, and a scalable extension point for downstream customization. Technologies/skills demonstrated: test version alignment, conditional logic for build optimization, extensibility hooks, and .NET SDK props management.
