实体框架提供商类型'Oracle.ManagedDataAccess.EntityFramework“无法加载 [英] The Entity Framework provider type 'Oracle.ManagedDataAccess.EntityFramework' could not be loaded

问题描述

我试图用连接到Oracle的Oracle数据Provider.NET（ODP.NET）使用MVC应用程序中的实体框架V6。

I am trying to connect to Oracle using the Oracle Data Provider.NET (ODP.NET) using Entity Framework v6 in an MVC application.

我已经安装了ODP.NET从这里：
https://www.nuget.org/packages/odp.net .entityframework / 6.121.1-β

I have installed ODP.NET from here: https://www.nuget.org/packages/odp.net.entityframework/6.121.1-beta

我已经配置我的web.config文件如下：

I have configured my web.config file as follows:

<connectionStrings>
    <add name="MyDB" connectionString="User ID=MyUser;Password=MyPassword;Data Source=MyDatabase; Persist Security Info=False" providerName="Oracle.ManagedDataAccess" />
</connectionStrings>



<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>

然而，当我尝试打电话给我的EF情况下，我得到以下错误：

However, when I try to call my EF Context, I get the following error:

实体框架提供商类型'Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices，Oracle.ManagedDataAccess.EntityFramework，版本= 6.121.1.0，文化=中性公钥= 89b483f429c47342'在与ADO.NET提供应用程序配置文件中注册不变的名称'Oracle.ManagedDataAccess.EntityFramework无法加载。确保程序集限定名称的使用和该组件提供给运行的应用程序

The Entity Framework provider type 'Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices, Oracle.ManagedDataAccess.EntityFramework, Version=6.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' registered in the application config file for the ADO.NET provider with invariant name 'Oracle.ManagedDataAccess.EntityFramework' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application

我花了很多时间寻找这方面的帮助。将是任何帮助非常感谢！

推荐答案

添加本节进行到web.config中，与上述步骤一起，似乎已经解决了这个问题：

Adding this section to the web.config, along with the steps above, seems to have fixed this:

<system.data>

    <DbProviderFactories>

      <add name="ODP.NET, Managed Driver"
           invariant="Oracle.ManagedDataAccess.Client"
           description="Oracle Data Provider for .NET, Managed Driver"
           type="Oracle.ManagedDataAccess.Client.OracleClientFactory, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    </DbProviderFactories>

</system.data>
