Thanks for the review. I will need you to commit on my behalf. I think its about time I figure out what conditions I need to meet in-order to get commit after approval rights.

`/Fopath.cpp` is super unreadable. Unfortunately, I don't remember when the colon spelling came into existence but anything from VS2017 definitely has the colon alternative spelling.
