如何重新映射程序集Oracle.DataAccess从版本'2.112.2.0'到'2.112.3.0'的app.config

Question

我是C＃的新手。

我写了一个C＃控制台应用程序，它使用ODP使用Oracle.DataAccess.Client命名空间与Oracle数据库连接。我的开发机器使用Oracle.DataAccess版本2.112.2.0，开发服务器也使用Oracle.DataAccess版本2.112.2.0，并且程序工作正常。 prod服务器使用更高版本的Oracle.DataAccess ver 2.112.3.0，并且该程序不运行，并且出现以下异常。

Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'Oracle.DataAccess, Version=2.112.2.0, Culture=neutral, PublicKeyToken=89b483f 
429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) 
File name: 'Oracle.DataAccess, Version=2.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342' 
    at OPSegmentTDs.Programu.Main(String[] args) 


I tried installing ODAC for Oracle client 11.2.0.3.0 on my dev machine and added the higher ver of Oracle.DataAccess reference 2.112.3.0 in my application and when I built it I got this warning but the program built successfully. 

Consider app.config remapping of assembly "Oracle.DataAccess, Culture=neutral, PublicKeyToken=89b483f429c47342" from Version "2.112.2.0" [] to Version "2.112.3.0" [C:\Oracle\OraODP1123\product\11.2.0\client_2\ODP.NET\bin\2.x\Oracle.DataAccess.dll] to solve conflict and get rid of warning.

当我想我的督促服务器上运行的新构建的应用程序与相同的错误

尝试复制甲骨文的DLL文件的正确版本（从ODAC112030Xcopy_32bit.zip或ODAC112030Xcopy_x64.zip崩溃）下的应用程序的bin/setup文件夹中，并将以下内容添加到应用程序的app.config中：

<system.data> 
    <DbProviderFactories> 
     <remove invariant="Oracle.DataAccess.Client" /> 
     <add name="Oracle Data Provider for .NET" 
      invariant="Oracle.DataAccess.Client" 
      description="Oracle Data Provider for .NET" 
      type="Oracle.DataAccess.Client.OracleClientFactory, Oracle.DataAccess, Version=2.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342"/> 
    </DbProviderFactories> 
</system.data>
