for every one watching this video important fix for you : use Oracle.ManagedDataAccess.dll instead of Oracle.DataAccess.dll (you can search for it in oracle home directory) and copy tnsnames.ora file to same path of your output exe file i assure to you that vs2010 and may be higher virsions will connect to oracl 12c database successfully using this way , god bless bye..

Thanks for the video! Very useful. Speaking of my experience, I prefer using dotConnect for Oracle https://www.devart.com/dotconnect/oracle/ . Very fast and reliable. Have you ever tested it out?
