It is decidedly not trivial because people can and do choose to install Visual Studio to any random path they want. You can't assume that it is in C:\Program Files (x86) or %ProgramFiles(x86)% or anything like that, if you care about making reliable software. And there is no guarantee that future versions won't change the directory structure again. In fact there's practically a guarantee that they will someday. I am well aware that you can use the developer command prompt (in which case you don't need to run that command at all, it would be redundant). But it's a ridiculous and extremely annoying requirement to impose on your users.
