使用ODP.NET 64位的.NET Web服务 [英] .NET Webservice using ODP.NET 64bit

问题描述

我在.net4.0中创建了一个Web服务.它通过ODP.NET4连接到oracle数据库.仅供参考，我使用了ODAC112021Xcopy_X64并安装了odp4和asp4.该服务在开发环境中运行良好.

I created a web service in .net4.0. It connects to an oracle-database by ODP.NET4. FYI I used ODAC112021Xcopy_X64 and installed odp4 and asp4. The service runs well in development environment.

但是将其发布到在同一台计算机上运行的IIS之后，出现以下异常:

But after publishing it to IIS running on the same machine I get the following exception:

System.ServiceModel.FaultException`1 was unhandled
  Message=Could not load file or assembly 'Oracle.DataAccess, Version=2.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
  Source=mscorlib

我使用64位odp.net，我在64位Windows Server 2008 R2上运行，并在Visual Studio中切换到64位.

I use 64bit odp.net, I'm running on Windows Server 2008 R2 64bit and switched to 64bit in Visual Studio.

有人可以告诉我我想念什么或做错什么吗?

Can anybody tell me what I'm missing or doing wrong?

我还尝试将ORACLE.DATACCESS.dll复制到bin文件夹.

I also tried to copy the ORACLE.DATACCESS.dll to the bin folder.

预先感谢

推荐答案

检查编译器计算机(32/64位)中的ODAC目标平台是否与放置Web服务的生产服务器相同.

Check if ODAC target platform in your compiler machine (32/64 bit) is the same of production server where you put your web services.
