在asp.net中使用WCF时出错

Question

我通过向项目添加服务引用来使用wcf，然后将web.confing更改为

<?xml version="1.0"?>

</configuration>

但我总是会得到异常

在ServiceModel客户端配置节中找不到引用协定'ServiceReference.IServices‘的默认终结点元素。这可能是因为找不到应用程序的配置文件，也可能是因为在客户端元素中找不到与此协定匹配的终结点元素。

模块system.serviceModel在库或站点中重复

你知道怎么解决这个问题吗？

Answer 1

这是一个服务端配置

<service name="DreamServices.DreamService">

客户端配置是什么样子的？它应该有一个带有contract="DreamServices.IServices"的client元素，或者您的约定的名称是什么。
