配置系统无法使用<system.serviceModel>进行初始化

我正在尝试制作一个客户端,通过WCF将消息放入服务器上的队列中。使用各种网站、论坛帖子等的组合,我已经根据下面的App.config编写了代码。

当我执行检索CryptoCoordinatorQueueName的简单操作时,我会得到一个异常。如果我注释掉system.serviceModel和bindings部分,异常就会消失,并且正确返回字符串。异常是“配置系统未能初始化”,向下挖掘,我看到了内部异常“无法识别的元素”和与标记对应的行号。项目引用了System.ServiceModel,但这似乎不足以使配置系统接受该元素。有人知道怎么解决这个问题吗?我正在使用dotnet4和VS2010。
