Note:
Entity Framework 6 is not supported at this time. Some Visual Studio versions may default to Entity Framework 6. If so, set your .NET project to use an earlier version of Entity Framework.
The message is provided in the Oracle Data Provider's system requirements
Is this the status still the same for today, or am I seeing an old message.
I am aware of dotConnect for Oracle from Devart.
Jacek Glen :
Entity Framework 6 is still not supported by ODAC 12c (or any other version). Supported EFs are 4.5 and 5. Third party products, e.g. Devart, seems to be the only option at the moment. \nI haven't seen any announcement from Oracle to indicate possible release date.",
