Directx 11.3 versus 12?

[Cromulent]

I want to build a simple game on Windows 10 and was wondering if I should start with Directx 11.3 or 12?

Ive never made a game before so I want the simpler options. I'm prepared to build the game in C++ using Visual Studio.

Any tips on books for this challenge?

AFAIK DX11.3 is a Feature Set of DX12 announced at same time but they decided to just go DX12 instead of DX11.3

Thanks for your reply. Ah I see now. Well that simplifies things I'll just have to buy a book on DirectX 11 then.i don't think I am ready for DirectX 12 yet.
