使用Oracle.DataClient时,提供程序与Oracle客户端错误的版本不兼容

我正在使用Visual Studio 2008 Express Edition,我正在尝试使用Oracle.DataClient开发一个小型应用程序。 我在尝试连接到目标系统中的数据库时遇到上述错误。

在发布这篇文章之前,我读了 this post 现在,我已经安装了即时客户端,错误仍然存在。 下面是完整的错误堆栈。

我在开发应用程序的机器上安装了Oracle11g,它在那里运行良好,但在目标机器上,我遇到了这个错误。 如有任何意见,将不胜感激。

PS:如上所述,引用的Oracle.DataClient.dll文件版本对应于10gR2,而不是11g。
