Kurt Kennett expanded build compatibility for the microsoft/mu_basecore repository by enabling support for the Visual Studio 2022 ARM64 toolchain. He adjusted include guards, refined assembly macro definitions, and implemented conditional compilation to support MSVC ARM64, leveraging his expertise in ARM architecture, build systems, and embedded systems. Working primarily in C and Assembly, Kurt’s changes established cross-compiler and cross-architecture build compatibility, laying the foundation for ARM64 continuous integration and release pipelines. This work reduced manual build friction and accelerated iteration cycles, ultimately streamlining onboarding for ARM64 contributors and improving the overall development workflow for the mu_basecore project.
