[英]Can't add WCF service reference to client project using netTcpBinding
I have a WCF service that uses NetTcpBinding and I'd like to host it in a WPF application. 我有一个使用NetTcpBinding的WCF服务,我想将其托管在WPF应用程序中。 The service seems to start correctly, but when I'm trying to get it's metadata using 'Add service reference' in visual studio I get this exception:
该服务似乎正常启动,但是当我尝试在Visual Studio中使用“添加服务引用”获取其元数据时,出现此异常:
The URI prefix is not recognized.
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:8000/Mandrake/mex'.
My service project's App.config file: 我的服务项目的App.config文件:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
<services>
<service name="Mandrake.Service.OTAwareService">
<endpoint address="OTService" binding="netTcpBinding" contract="Mandrake.Service.IOTAwareService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint name="MEX" address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8000/Mandrake/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata/>
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
And the code in the hosting application: 以及托管应用程序中的代码:
Uri baseAddress = new Uri("net.tcp://localhost:8000/Mandrake");
ServiceHost host = new ServiceHost(typeof(OTAwareService), baseAddress);
try
{
host.AddServiceEndpoint(typeof(IOTAwareService), new NetTcpBinding(), "OTService");
}
catch (CommunicationException e)
{
Console.WriteLine(e.Message);
host.Abort();
}
The solutions I found to the problem were mainly about adding the 'serviceMetaData' to the service config or providing a mex endpoint. 我发现的问题解决方案主要是将'serviceMetaData'添加到服务配置中或提供mex端点。 Could you suggest something?
你能建议点什么吗?
Edit: 编辑:
Final config: 最终配置:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="NewBehavior0">
<serviceMetadata />
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="Mandrake.Service.OTAwareService" behaviorConfiguration="NewBehavior0">
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8036/OTService"/>
</baseAddresses>
</host>
<endpoint address="" binding="netTcpBinding" name="TcpEndpoint" contract="Mandrake.Service.IOTAwareService" />
<endpoint address="mex" binding="mexTcpBinding" name="MetadataEndpoint" contract="IMetadataExchange" />
</service>
</services>
</system.serviceModel>
Hosting application: 托管应用程序:
host = new ServiceHost(typeof(OTAwareService));
host.Open();
I've managed to figure it out, after enabling the serviceDebug's includeExceptionDetailInFaults it was pretty clear. 在设法启用serviceDebug的includeExceptionDetailInFaults之后,我设法弄清楚了这一点。
Mandrake.Service.IOTCallback.Send operation references a message element [http://tempuri.org/:Send] that has already been exported from the Mandrake.Service.IOTAwareService.Send operation
So there was a Send(OTMessage) operation in the service contract and in the callback interface as well. 因此,在服务协定和回调接口中也都有一个Send(OTMessage)操作。 A rather ugly mistake but I thought I would leave the solution here in case it helps anyone.
这是一个相当丑陋的错误,但我想我会把解决方案留在这里,以防万一。
