Ich habe den gleichen Fehler und ich wurde wie folgt festgesetzt: Sie benötigen eine Web ändern. Konfiguration wie folgt:

<entityFramework> 
    <defaultConnectionFactory type="Oracle.ManagedDataAccess.EntityFramework.OracleConnectionFactory, Oracle.ManagedDataAccess.EntityFramework"></defaultConnectionFactory> 
    <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> 

Und Sie müssen EntityFr installieren amework 1. Install-Package EntityFramework -Version 6.1.1 2. Fügen Sie einen Verweis von Ihrem Link-Setup ODAC 12c Release 4 Oracle.ManagedDataAccess.EntityFramework.dll Oracle.ManagedDataAccess.dll zu Ihrem Projekt hinzu. Es ist getan
