试试下面这个例子：

服务器web.config的下面部分

  <services>
      <service name="Service1.svc.cs"  >
        <endpoint address="" binding="basicHttpBinding"
                  bindingConfiguration="Service1"
                  contract="IService1" >
        </endpoint>
      </service>
    </services>

具有错误属性的某些值。服务元素的name属性值需要为namespace.Service1，类似地，endpoint元素的contract属性值需要为namespace.IService1，如下所示：

  <services>
      <service name="<namespace>.Service1"  >
        <endpoint address="" binding="basicHttpBinding"
                  bindingConfiguration="Service1"
                  contract="<namespace>.IService1" >
        </endpoint>
      </service>
    </services>

只需替换为Service1类的名称空间。这应该行得通
