首先安装ODAC 12c第3版,其中包括对实体框架6代码优先和代码优先迁移的支持; NuGet,.NET Framework 4.5.2;和ODP.NET,托管驱动程序XML DB.按照

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

将两个引用添加到我的项目引用中,它们是：

Oracle.ManagedDataAccess.dll

Oracle.ManagedDataAccess.EntityFramework.dll

通过在程序包管理器控制台中运行以下命令,使用NuGet安装EF6.1.1(可以通过Tools-> NuGet程序包管理器 – >程序包管理器控制台输入)：

Install-Package EntityFramework -Version 6.1.1

并修改您的web.config或web.config以使用Oracle.ManagedDataAccess,方法是添加Provider和有效的连接字符串,例如：

<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,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,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>

将您的应用程序重建为x86,并开始使用EF6,您可以使用代码优先使用ADO.Net实体模型添加模型来检查它是否有效
