Oracle ODP.Net With Entity Framework 6 - Entity framework database compatible provider could not be found

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 Framework 6 Code First and Code First Migrations; NuGet, .NET Framework 4.5.2; and ODP.NET, Managed Driver XML DB. As per

http://www.oracle.com/technetwork/topics/dotnet/whatsnew/index.html

I have VS 2013 Community Edition update 4 .

Am trying to add Model using ADO.Net Entity Data Model , With Code First.

I have the following configured in my Web.config

    <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    <section name="Oracle.ManagedDataAccess.Client"
             type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />


  </configSections>

  <entityFramework>
    <contexts>
      <context type="Tamayz.Context.Default, Tamayz.Context">
        <databaseInitializer type="MyProject.Context.Config.ContextInitializer, MyProject.Context" />
      </context>
    </contexts>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="Oracle.ManagedDataAccess.Client" 
                type="Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices, Oracle.ManagedDataAccess.EntityFramework, Version=6.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    </providers>
  </entityFramework>

I also added Oracle.ManagedDataAccess version 4.121.2.0 as a reference and rebuild the solution.

I tried now to add Model using ADO.Net Entity Data Model , With Code First. but am getting the following message in the last screen of the wizard:

Your project references that latest version of entity framework; however, an Entity Framework database Provider compatible with this version could not be found for your connection...

How could I properly configure my application to be able to use ODAC with EF6 Code first ?

I finally was able to to use ODP with EF6.

I did the following to make it work :-

First Installing ODAC 12c Release 3 which includes support for Entity Framework 6 Code First and Code First Migrations; NuGet, .NET Framework 4.5.2; and ODP.NET, Managed Driver XML DB. As per

http://www.oracle.com/technetwork/topics/dotnet/whatsnew/index.html

Adding two references , to my project references and they are :

Oracle.ManagedDataAccess.dll

Oracle.ManagedDataAccess.EntityFramework.dll

Installing EF6.1.1 using NuGet by running the following command in Package Manager Console( you can enter it by Tools->NuGet Package Manager -> Package Manager Console):

Install-Package EntityFramework -Version 6.1.1

And modify your web.config or web.config to use Oracle.ManagedDataAccess , by adding Provider and a valid connection string eg :

<configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    <section name="Oracle.ManagedDataAccess.Client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
  </configSections>
  <entityFramework>
    <contexts>
      <context type="App.Context.Default, App.Context">
        <databaseInitializer type="MyProject.Context.Config.ContextInitializer, MyProject.Context" />
      </context>
    </contexts>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="Oracle.ManagedDataAccess.Client" type="Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices, Oracle.ManagedDataAccess.EntityFramework, Version=6.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
  <connectionStrings>
    <add name="Default" providerName="Oracle.ManagedDataAccess.Client" connectionString="DATA SOURCE=XE;USER ID=User" />
  </connectionStrings>

Rebuild your Application as x86, and start using EF6 , you can check if it works by adding a model using ADO.Net Entity Model using Code First
