Question

我正在为我的应用程序实现WCF发现。一切正常，除了我们网络中的虚假交通在Wireshark的帮助下，我发现服务发送＆＃34; Hello＆＃34;，＆＃34;探测＆＃34;和＆＃34;解决＆＃34;消息到239.255.255.250:3702地址。根据WCF发现规范，客户端应发送＆＃34; Hello＆＃34;，＆＃34;探测＆＃34;查找服务和服务的消息应该发送公告＆＃34;您好＆＃34;使用托管发现时的消息据我所知，当没有搜索时，服务没有理由广播消息。客户应该发送＆＃34; Hello / Probe＆＃34;消息和服务应回答＆＃34; ResolveMatches / ProbeMatches＆＃34;消息一次。
有没有办法关闭服务的这种行为？

我的配置文件：
