You can achieve a lot of this by creating a blank virtual machine with "just the operating system" as a starting point and stepping through your own instructions from there.

My ideal state is that for my kind of .NET work, it should be sufficient to simply install the latest Visual Studio, check out the Git repo, and press "play".

That's not always possible, so then the exercise becomes to simply document each step, ideally with both English words and a CLI snippet.
