C# 如何在internet上承载WCF双工服务

我有一个带有WSDualHttpBinding的WCF服务，该服务在本地运行良好，当我在IIS上托管它时，它不工作，首先它要求提供登录凭据，而绑定上没有设置身份验证，但是，我现在将安全模式设置为“无”，当我从客户机发出请求时，它会一直等待响应并超时

任何建议或范例都将不胜感激

我上周遇到了同样的问题。我删除了这一行它运行良好。您可以在“本地”尝试它，IIS对您来说似乎是两件不同的事情，您是否尝试过在IIS中的PC上托管它以发现问题？发布您的配置将有所帮助。@nvoigt是的，它在我们的开发服务器IIS上工作，但一旦我将其部署到公司网络之外，我就面临problem@christiandev我已经用配置更新了问题。
