WCF服务报错

                                                                            
[解决办法]
你在VS中直接浏览svc能访问不一定 客户端就能调用
你先保证端口是通，再确保元数据能正确下载，如果不能下载元数据，客户端是生成不了代理类的，

你服务发布后 http://localhost:1678/Interface/UserInterface.svc改过没

把你client端config里的

bindingConfiguration="BasicHttpBinding_IUserInterface"这个发来瞧瞧看你的Binding是怎么配的，
通常我们做wcf开发的时候，会用svcutil.exe这工具来为我们生成代理类和config！
[解决办法]
你的服务端貌似没有设置端口号啊

看看下面这个配置
<span style="font-family:Times New Roman;font-size:18px;"><?xml version="1.0" encoding="utf-8" ?>
