I'm running the released version of VS2022. It seems my installation didn't get the "Embedded and IoT tools" checked by default under the "Linux and embedded development with C++" workload.
The problem I saw when building was:
CMake Error at C:/code/AzureRTOS/getting-started/cmake/arm-gcc-cortex-toolchain.cmake:31 (message):
Unable to find ARM GCC. Either add to your PATH, or define ARM_GCC_PATH to
the compiler location

-- Configuring incomplete, errors occurred!
ninja: error: loading 'build.ninja': The system cannot find the file specified.
After adding that, rebooting Windows, and re-running vcpkg activate, I was able to build fine.
