I'm trying to add an ADO.NET Entity Data Model to my solution which uses an Oracle database (ODP.NET), but I get the following error:
"Your project references the latest version of Entity Framework; however, an Entity Framework database provider compatible with this version could not be found for your data connection. If you have already installed a compatible provider, ensure you have rebuilt your project before performing this action. Otherwise, exit this wizard, install a compatible provider, and rebuild your project before performing this action."
The dialog also says it is trying to use Entity Framework 6.x.
I'm using Visual Studio 2013, and it's an ASP.NET MVC 5 web application. I have installed 64-bit ODAC 12c Release 3 (18.104.22.168.1) for Windows x64.
You have to install 32-bit Oracle Data Access Components (ODAC)
with Oracle Developer Tools for Visual Studio.
You can download it from Oracle web site.
