可靠性绘画答条件：

           （1）服务绑定支持可靠性绘画：特别是netTcpBinding、wsHttpBinding及wsDualHttpBinding.

                         wsDualHtttpBinding可靠性绘画始终都是可用的，不须要配置，然上面的其他两种须配置，以wsHttpBinding为例，配置如下：

                                         <wsHttpBinding>

                                              <binding  name="mybinding" >

                                                    <reliablesession   enabled="true"  ordered="true" inactivityTimeout="00:10:00" />     <--最后一个属性表示提高闲置超时时间-->

                                              </binding>

                                         </wshttpBinding>

                  当然你也可以使用定制绑定  <customBinding>(推荐)设置更丰富(详情百度！)

ServiceThrottleBehavior提供了很多吞吐量控制的设置：

 （1）MaxConcurrentCalls: 限制并发请求(也就是同时向服务器发送请求的个数)– 缺省为16

 （2）MaxConcurrentInstances: 限制服务实例的数量(也就是服务端创建的服务实例的个数)– 缺省为int.MaxValue，该值一般大于等于maxConcurrentCalls;

 （3）MaxConcurrentSessions:限制活动会话数量，包括传输，可靠性与安全会话和应 用程序会话– 缺省10 

  <serviceThrottling maxConcurrentCalls="30" maxConcurrentInstances="2147483647" maxConcurrentSessions="30" />

下面是完整配置：

   <system.ServiceModel>

        <wsHttpBinding>

            <binding  name="mybinding" >

                    <reliablesession   enabled="true"  ordered="true" inactivityTimeout="00:10:00" />     <--最后一个属性表示提高闲置超时时间-->

            </binding>

        </wshttpBinding>
