MySQL Connector : Runtime Error issue

I've looked everywhere for help,I am legit a dummy when it comes to figuring out these types of errors. I've found one possible solution but it didn't seem to work.

Unity Version: 2017.3.1f1

Possible solution below(doesn't work for me): CodeDojo

Download site for connector: MySQL Connector

I put the connector .dll files in unity asset folder and everything compiles, but it does not work when running, which throws all sorts of errors based on the version of the MySql Connector. Same code transferred over to just VS 2017 by itself works fine.

I set unity to use .NET 4.6 or otherwise it really wouldn't work. I use the

System.Data located in Unity/Editor/Data/MonoBleedingEdge/lib/mono/unityjit

otherwise VS wont recognize the imports and references and this this is the only one that seems to get it to compile in VS 2017. I reimport all after each version test.

Latest Version: mysql-connector-net-8.0.11 error:

These only happen during runtime. Any help would be greatly appreciated. Or any pointers to any location that may help.
