Post Edit: ( for the records)
so what was I actually missing when I initially logged the issue 
- This---->: ’ I remember I got owned on the ASP course because at the time Mosh did the course the default was to add Identity by default so he didn’t even mention’
I went ahead and installed this (just with a Gut feeling & nothing more!)
- and this : ‘Maybe as a beginner go checking that box so that it reflects what you’ll meet in the course.’
And from here I was game ( at least so far)
The rest of the information is ‘nice’ but is not geared for a rookie who has just started with the course & also installing ‘V.S’ the very 1-st time. I mean Mosh tells prior to his course : No prior knowledge is needed,
quote : * Anyone who wants to learn programming for the first time. unquote
Mosh should have mentioned a few more lines on how to get the V.S working , at least just for the course’s sake, rather than just stating a URL & suggesting to ‘seek out the rest’.
These kind of installation issues(in real life) are done by the system-admin and we do not have an exact idea because it does not belong to our daily tasks. For example , it’s just like asking a seasoned SAP Logistic or Finance consultant to install & config. SAP on a clean machine, I’m pretty sure that person will have some vague idea about it , but can never fulfil the task alone( with 1 install url).(exceptions barred)
anyway, as I mentioned, the above two points helped me wade out through my first swamp, I hope the course goes smoothly from here without too many of the ‘swamp things’ 
And did I say : Many Thanks UniqueNospaceShort !
