Oracle.ManagedDataAccess系统找不到指定的文件

Question

在我基于Oracle.ManagedDataAccess.dll 3.5构建的网站项目中，当我在web.config中添加对web.config的引用时

<add assembly="Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89B483F429C47342"/>

它给出了这个错误

Configuration Error 
  Description: An error occurred during the processing of a configuration file required to     service this request. Please review the specific error details below and modify your configuration file appropriately. 

 Parser Error Message: Could not load file or assembly 'Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.

Answer 1

此错误出现在.net版本3.5时，解决方案是将.net版本升级到.net 4.0或更高版本。
