求大神么帮帮忙吧 ，周一就要给客户部署了 现在又可以运行了 下班前部署到的公司外网上，回家运行短时间 没问题 突然就出现上面的问题了 然后查了半天资料回过头来有试了一次居然又能登陆了 这要我好纠结

用浏览器抓包，IE10/11之类的话F12 开发人员工具，看你的silverlight请求的wcf返回的是什么，不出意外是500错误，然后有相关报错，无法访问的时候你直接浏览器里访问wcf的url看会不会报错

最近还是老是出现，我贴一下 我WCF 引用的一些配置 web.config <behaviors> <serviceBehaviors> <behavior name=""> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="50" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_Service" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"> <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647" /> </binding> </basicHttpBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> <services> <service name="GDInfoGasManager.Host.Service"> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Service" contract="GDInfoGasManager.Host.Service" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service>

ServiceReferences.ClientConfig 引用wcf <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_Service" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:8015/Service.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Service" contract="ServiceReference.Service" name="BasicHttpBinding_Service" /> </client> </system.serviceModel> </configuration>

下面是wcf调用 public static ServiceClient GetServiceClient() { BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None); binding.MaxReceivedMessageSize = int.MaxValue; binding.MaxBufferSize = int.MaxValue; ServiceClient client = new ServiceClient(binding, new EndpointAddress( new Uri(Application.Current.Host.Source, "../Service.svc"))); return client; }
