IP端点0.0.0.0:9000上通信对象和侦听器的WCF异常

Question

我在以下两件事上得到了WCFexception

通信对象System.ServiceModel.ServiceHost不能用于通信，因为它处于故障状态。

IP端点0.0.0.0:9000上已经存在一个侦听器。 确保您没有尝试在应用程序中多次使用此终结点，并且没有其他应用程序在此终结点上进行侦听。

如果尝试浏览，将显示无法显示页面的消息。如果重新启动服务器/服务，它将开始工作。 我是WCF的新手。 请帮助我解决问题。

提前致谢。

我假设您在Visual Studio中遇到此错误。转到项目文件的属性。 在“ Web”选项卡中找到项目URL。 您会找到类似http：// localhost：9000 /的网址。 在此处为http：// localhost：11483 /这样的名称指定其他端口号
