Answer 1

I had same problem and solved adding to my C# Project References Oracle.ManagedDataAccess instead of Oracle.DataAccess.
To do this go to (Tools / Nugget Package Manager / Nugget Package Manager for Solution) browse for Oracle References and select Oracle.ManagedDataAccess.
Then you need to comment or delete your actual DataAccess calls to ManagedDataAccess as:

//using Oracle.DataAccess.Client; 
//using Oracle.DataAccess.Types;
using Oracle.ManagedDataAccess.Client;

No need to change your Connection Code, only the using coding. After it works you can delete Oracle.DataAccess from your Project References
