Unity 2017.1 - Build to PC results in errors

I just downloaded 2017.1, have my project imported and it plays fine no errors. When I go to File>Build and try to build for PC, i hit build and nothing happens, then i proceed to play my scene again and it behaves unplayable now. Also now all the scripts in my hierarchy have a yellow exclamation point that say "The associated script can not be loaded. Please fix any compile errors and assign a valid script". There are no compile errors. Then i go into VS 2017 and there's missing references to all Unity libraries. I am unable to fix.

 

Well i tried with Unity 5.6 and it's the same. I recently had a team member check in some changes and everything got wonky... The game and scene plays fine until I try to go to build... then even if i restart unity the scripts all remain missing with yellow exclamation points. Does anybody know why this is?

 

So here's unity after I try to build for any platform using File>Build. The build selection does not load the normal "compiling" progress bar the program flickers and then loses control back to unity.




Before I build I can play, debug and breakpoint in V.S... after wards I cannot. I have to go to Assets>Reimport All Assets to have a playable scene again.


After i hit build, the breakpoints in visual studio debugger show exclamation points as well, that say when hovered over: "The breakpoint will not currently be hit. Unable to find a corresponding location"

One thing i noted is if i went to build player settings and changed api to .net 2.0 instead of .net 2.0 subset, the scripts are magically found again. Until i try to build to platform...



Heres the end of the editor.log file:

There was a build error, that apparently makes all the scripts in the scene say associated script is missing along with visual studio errors... strange, but fixed script and done. Do I feel green...
