In March 2025, Caizhi Zhang enhanced the BenchmarkDotNet repository by implementing .NET 9.0 runtime support, including both NativeAOT and Mono environments. Using C# and leveraging expertise in .NET development and benchmarking, Caizhi extended the RuntimeMonikerExtensions to recognize new 9.0 monikers, ensuring compatibility with the latest runtime versions. This update addressed a gap in BenchmarkDotNet’s ability to benchmark applications on .NET 9.0, preserving the integrity of existing workflows and continuous integration checks. The work demonstrated a focused approach to runtime support, enabling users to obtain accurate performance metrics on evolving .NET platforms while maintaining backward compatibility and workflow stability.
