Oracle Data Provider for .NET with Entity Framework 6.0

Question

I have a problem with Oracle Data Provider for .NET. I have:

• just disinstalled and reinstalled new version of Oracle, I have now 12.1.0
• Visual Studio 2015
• Oracle Developer Tool for Visual Studio

I want to create a ASP.NET Web Application with Entity Framework 6.0. If I open one of my old projects or when I create a new one and download from Nuget Oracle.ManagedDataAccess and Oracle.ManagedDataAccessEntityFramework this appears:

and if I click OK, I continue and create a model based on Oracle it always says that my EntityFramework is not correct for that provider even if I followed this link or it crashes after setting the connection and click "Next".

What's wrong? Please help me..

Answer 1

Thats how I solved it:

Remove all folders wich names contains "Oracle" from:

1. Windows\\Microsoft.NET\\assembly\\

2. Windows\\assembly\\

Then restart Visual Studio and it will work.

I used cmd in administrator mode to do that, because explorer or other file managers did not allow me to remove that folders.
