Can't Package Project in 4.16. Error C2061, C2504, C3646, C4430, C2614

I tried creating anew project with the marketplace version using the launcher 4.16.1 version and it did package. Is there a way I could obtain the code from the market place version quickly? When I open it in VS it doesn’t allow me to explore to disk.

How do I check if I have the Unity Builds disabled?
