我正在使用Visual Studio 2012构建 Web 应用程序。该应用程序使用 Web 表单、Ent​​ity Framework 5 和 IBM DB2 数据库服务器。我的开发机器和 Web 服务器上都安装了最新的 IBM Drivers v10.1.2。Web 服务器正在运行Windows Server 2008 R2 Standard x64bit OS。

问题我在本地机器上的 Visual Studio 的IIS Express下运行应用程序工作正常，但是当我将应用程序部署到 Web 服务器时，我遇到了 EF 和 DB2 驱动程序问题。这是错误和堆栈跟踪。做错了什么？！

我遇到了同样的问题，将应用程序池更改为网络服务就可以了。
