WCF customBinding问题

Question

我一直在玩一个让我疯狂的pollingDuplex示例。我正在使用customBinding来集成readerQuotas元素并且我不断收到错误：“Contract需要Duplex，但绑定'BasicHttpBinding'不支持它，或者没有正确配置以支持它。” 当我使用customBinding时，BasicHttpBinding来自哪里？我已经检查了无数的例子，我的配置文件与他们所拥有的相匹配，但它不起作用。谁能帮我这个 ？ 感谢。

Answer 1

httpGetEnabled="true"是否有可能暗示使用BasicHttpBinding？你真的需要这个功能吗？如果你评论这一行，错误会消失吗？

Answer 2

您可能遇到了“简化配置”问题 - 详见http://blogs.msdn.com/b/endpoint/archive/2009/11/09/common-user-mistake-in-net-4-mistyping-the-service-configuration-name.aspx。 <service>元素中的“name”属性必须是服务的完全限定名称。由于您的界面为AdminWebService.IAdminWebService，因此您的服务名称AdminWebService.AdminWebService不是？如果是这样，修复name属性应解决问题。
