Random Editor issue..5.3.1.2 | seems VS 2016 is causing editor to turn all warnings into errors..

It happens in all my projects, and it only happens after I open VS (double click on script), make a script change, hit save…I can fix ‘one’ of the errors(warnings), unity re compiles…and Editor comes back to normal…for awhile…then back to that behavior,

This is blocking my development chi…(I could fix every single warning)…

here is the thing…under ‘preferences’, attach to editor…I can not Turn that Off…EVER…
I unchecked it, restart unity…it is active again…(that is the problem)

already dumped the library, etc…(that is not the problem)

I looked for anything similar here…nothing

So VS Studio says I have no errors, yet unity says I have many…there is some kinda of disconnect with the two.

Has anyone experienced anything similar?

what it looks like

after I close Visual Studio…

It happened to me before. When certain compiler errors happen, Unity console reports all warning as errors. The actualy compiler error won’t be shown.

One is trying to declare a Vector3 as constant

const Vector3 test = Vector3.zero;
