I am trying to build an MVC 5 Web application with Entity Framework 6 that works on Oracle Database , am trying to use ODAC 12c Release 3 which includes support for Entity F
For me, installing this Nuget packages works. https://www.nuget.org/packages/Oracle.ManagedDataAccess.EntityFramework/
I also downgraded to 6.1.2 and all my problems with adding an Entity Model disappeared. It seems both 2015 and 2017 Visual Studio have problems with versions any higher than that. Oracle need to look at this ASAP.
