协定须要双工,可是绑定“WSHttpBinding”不支持它或者因配置不对而无法支持它

下面两种情况,我都遇到过。

一,

 < endpoint address ="" binding="wsHttpBinding" contract="异步.IService1">中的wsHttpBinding改为wsDualHttpBinding,client又一次更新server引用就可以



二。app.config

在<system.serviceModel></system.serviceModel>之间加上



<protocolMapping>

<add scheme="http" binding="wsHttpBinding" bindingConfiguration="WsHttpSession"/>

</protocolMapping>
