ok, I'll leave the cross-compilation instructions in place.

> I think what you are talking about is the fact that, at least currently, the BuildTools distribution of Visual Studio do not include aarch64-hosted compilers, so to be able to run native builds without the Prism emulation, you need to install the full Visual Studio, including the IDE. This too might be worth documenting, with the caveat that it applies currently but might change in the future.

taking another look at the build tools, will update this docs PR by end of week
