Mono WCF客户端异常：所请求的功能未实现

Question

I have developed a C# WCF client application using Visual Studio 2008 and it works fine. The client application uses the wcf wrapper class and consume the WCF service. But when I execute the same source code in Redhat Linux 6.5 using MonoDevelop IDE, I am getting the following exception while creating a wcf object. The WCF web service is running as a windows service.

{System.NotImplementedException: The requested feature is not implemented. at System.ServiceModel.Configuration.WSHttpBindingElement.OnApplyConfiguration (System.ServiceModel.Channels.Binding binding) [0x00000] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel.Configuration/WSHttpBindingElement.cs:101 at System.ServiceModel.Configuration.StandardBindingElement.ApplyConfiguration (System.ServiceModel.Channels.Binding binding) [0x00030] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel.Configuration/StandardBindingElement.cs:143 at System.ServiceModel.Configuration.ConfigUtil.CreateBinding (System.String binding, System.String bindingConfiguration) [0x00053] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel.Configuration/ConfigUtil.cs:104 at System.ServiceModel.ChannelFactory.ApplyConfiguration (System.String endpointConfig) [0x000e9] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ChannelFacto ry.cs:156 at System.ServiceModel.ChannelFactory.InitializeEndpoint (System.String endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) [0x00024] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ChannelFactory.cs:309 at System.ServiceModel.ChannelFactory 1[IMyMonitor]..ctor (System.String endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) [0x00017] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ChannelFactory_1.cs:73 at System.ServiceModel.ClientBase 1[IMyMonitor].Initialize (System.ServiceModel.InstanceContext instance, System.String endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) [0x00000] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ClientBase.cs:159 at System.ServiceModel.ClientBase 1[IMyMonitor]..ctor (System.ServiceModel.InstanceContext instance, System.String endpointConfigurationName) [0x00028] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ClientBase.cs:90 at System.ServiceModel.ClientBase 1[IMyMonitor]..ctor (System.ServiceModel.InstanceContext instance, System.String endpointConfigurationName) [0x00028] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ClientBase.cs:90 at System.ServiceModel.ClientBase 1[IMyMonitor]..ctor (System.ServiceModel.InstanceContext instance) [0x00000] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ClientBase.cs:79 at System.ServiceModel.ClientBase`1[IMyMonitor]..ctor () [0x00000] in /home/abuild/rpmbuild/BUILD/mono-3.4.0/mcs/class/System.ServiceModel/System.ServiceModel/ClientBase.cs:54 at SenMonitorClient..ctor () [0x00000] in /mywork/myclient/wcfService.cs:1429 at myclient.start () [0x0079c] in /mywork/myclient/Program.cs:285 } System.NotImplementedException

Thanks for your help.

WCF support is currently limited on Mono and as mentioned here - mono-project.com/WCF WSHttpBinding and its dependencies are components with no plan to support. May be you want to fall back on to basichttpbinding which should be supported since it shows WCF modules were in development till .NET 3.0 with silverlight 2.0 subset.
