Thanks for expanding on that. Do you know when ARM64 support was added? As in, which version of Visual Studio first supported ARM64 POGO? If this is a more recent addition than ARM64 support in general, it's useful to let readers know they need to update their VS to get the feature.

Hello Colin, I don't know when it was added, but I don't think it was the very latest. At least Visual Studio 2019 / toolchain v142 and 2022 toolchain v143 support it, but likely earlier. Internally we (*) have been optimizing ARM64 a few years already. For the first few years Visual Studio just did not release the binaries public. Hence I suspect the moment ARM64 became officially supported we started immediately supporting PGO too. Regards, Armin *) and in this case I literally mean our team. As we are responsible for PGO optimization of Windows OS binaries. Hence why I noticed.
