关于wcf中wsDualHttpBinding的问题

[lyonyf]

利用wcf的回调机制，编写程序时，把服务发布到本地的IIS上调试没有问题，但发布到别的机器上，进行局域网内调试时，连接一直不能打开，报错为：
绑定类型：wsDualHttpBinding时出错，basicHttpBinding,wsHttpBinding时正常通信。

第一次发帖，请多指教：
错误提示整理了一下：

把配置文件发来看看。

[ZJ_CHENBF2008]

我遇到了你同样的问题，请问你有解决方法了吗？

[lyonyf]

我的那个问题的原因是配置文件中clientAddress的值设置为localhost:端口号，如果把localhost改为（相应机器）机器名，就可以了。

[子在川上笑]

更改配置文件app.config
<system.serviceModel>
<services>
<service name="WcfServiceLibrary1.MathService">
<endpoint address="" binding="wsHttpBinding" contract="WcfServiceLibrary1.IMathService">

将binding="wsHttpBinding"改为 binding="wsDualHttpBinding"就行了，为双工模式！
