I have a need to hook into an old service that is running via a Windows Service that launches a service host through HTTP at runtime. I can't seem to find out how to get my 'Add Service Reference" to work. I know the service is running as the log file shows that. Here's the config entries for the service:
<system.serviceModel>
<bindings />
<services>
<service behaviorConfiguration="blah.blah.WCF_Service.EngineServiceBehavior" name="blah.blah.WCF_Service.EngineService">
<endpoint address="http://localhost:8455/EngineService/" binding="basicHttpBinding" bindingConfiguration="" name="Engine" bindingName="EngineBinding" contract="blah.blah.IEngineService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" bindingConfiguration="" name="Mex" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8455/EngineService/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="blah.blah.EngineServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
It has a mex endpoint being set, but I can't see how to construct the url to get the service information.
Any thoughts?
looks like you need some details to add service reference.
in your project, right-click 'References' and select 'Add service reference ...' and enter the address John Saunders mentioned. and then click 'Go'.

I follow this blog CONFIGURING WCF SERVICE WITH NETTCPBINDING step by step, when I add service reference from VS 2013, I got below error.
The URI prefix is not recognized.
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost/WCFNetTcp/WCFNetTcpService.svc/mex'.
You have tried to create a channel to a service that does not support .Net Framing. It is possible that you are encountering an HTTP endpoint.
Expected record type 'PreambleAck', found '72'.
My Service configure file is below:
<system.serviceModel>
<services>
<service behaviorConfiguration="netTcpb" name="WCFNetTcp.WCFNetTcpService">
<endpoint address="" binding="netTcpBinding" bindingConfiguration="portSharingBinding" contract="WCFNetTcp.IWCFNetTcpService" />

</baseAddressPrefixFilters>

I tried any net.tcp URL what I could think out, but all of them do not work. It seems that basic address did not work when the service is hosted in IIS, it depends on the url in IIS. If I create a service which is hosted in console application with below configuration file, it works.
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="WCFNETTCP.Service1">
<endpoint address="" binding="netTcpBinding" contract="WCFNETTCP.IService1">
</endpoint>
<!--comment out after you add service reference-->
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://xxx:6666/WCFNETTCP/" />
<add baseAddress="http://xxx:6667/WCFNETTCIP"/>
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
It would be appreciated if you could share us how to make it work under IIS.
It seems there is something wrong in my IIS. I resolved this issue by below steps.
reinstall IIS
reinstall WCF Non-HTTP Activation in Windows features
reregister asp.net in iis by this command
C:\Windows\Microsoft.NET\Framework64\v4.0.30319>dism /online /enable-feature /featurename:IIS-ASPNET45
Check the settings in IIS which there is no change at my side.
Rebuild my WCF Service, and add service reference successfully.
Hope it will be work for you.
I'm get Machine Name in the WCF proxy and getting below exception while invoking WCF service
The remote server returned an error: (415) Cannot process the message
because the content type 'application/soap+xml; charset=utf-8' was

WSDL document contains links that could not be resolved. - There was

Can any one please help me fix this issue. And below is my web.config

Thanks for your response Tom.
I fixed this issue using
<behavior name="MyServiceBehaviour">
<serviceMetadata httpGetEnabled="true" />
<useRequestHeadersForMetadataAddress />
</behavior>
I have developed a WCF application in .net framework 3.5. The application is working fine but when I deploy it in iis it is giving blank when I have tried to access the webservice using the url
http://mysite:8086/VpoService.svc
my configuration file is like this.
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="VpoService.VpoServiceTypeBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="VpoService.VpoServiceTypeBehavior"
name="VpoService.VpoServiceType">
<endpoint address="" binding="wsHttpBinding" contract="VpoService.IVpoService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<!--<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />-->
</service>
</services>
</system.serviceModel>
Try modifying your <endpoint>
<host>
<baseAddresses>
<add baseAddress="http://MachineIP/VpoService.svc" />
</baseAddresses>
</host>
It worked for me
I have created a service host with following configuration.
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="MathServiceLib.MathService" behaviorConfiguration="myMathServiceBehave">
<host>
<baseAddresses>
<add baseAddress="http://localhost:9001/MathService"/>
<add baseAddress="net.tcp://localhost:9002/MathService"/>
</baseAddresses>
</host>
<endpoint address="http://localhost:9001/MathService" binding="basicHttpBinding" contract="MathServiceLib.IMathService"/>
<endpoint address ="net.tcp://localhost:9002/MathService" binding ="netTcpBinding" contract="MathServiceLib.IMathService"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<!--<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>-->
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="myMathServiceBehave">
<!--<serviceMetadata httpGetEnabled="true"/>-->
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
I don't want to use serviceMetadata httpGetEnabled="true" property instead I want to use MEX binding for proxy creation.
Now when I start my service using
svcHost = new ServiceHost(typeof(MathServiceLib.MathService));
svcHost.Open();
I get following error, please help.
The contract name 'IMetadataExchange' could not be found in the list of contracts implemented by the service MathService. Add a ServiceMetadataBehavior to the configuration file or to the ServiceHost directly to enable support for this contract.
Based on my experience, you need to specify
<serviceMetadata httpGetEnabled="true"/>
if you want to use
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>

I have a WCF Service which has it's configuration file as specified below:
<system.serviceModel>
<services>
<service name="WCFService.ServiceClass" behaviorConfiguration="metaDataSupport">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/WCFService"/>
<add baseAddress="net.tcp://localhost:8100/WCFService"/>
<add baseAddress="http://localhost:8101/WCFService"/>
</baseAddresses>
</host>
<endpoint address="tcpmex"
binding="mexTcpBinding"
contract="IMetadataExchange" />
<endpoint address="namedpipemex"
binding="mexNamedPipeBinding"
contract="IMetadataExchange" />
<endpoint address=""
binding="wsHttpBinding"
contract="WCFService.IServiceClass" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="metaDataSupport">
<serviceMetadata httpGetEnabled="false" httpGetUrl="" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
I have 3 types of binding here: NamedPipeBinding, TcpBinding and wsHttpBinding.
I can add a reference with metadata at the following location
net.tcp://localhost:8100/WCFService/tcpmex
net.pipe://localhost/WCFService/namedpipemex
I have disabled the httpGet for the service in behavior.
The service reference is added but with the following configuration at client:
<system.serviceModel>
<bindings>
<wsDualHttpBinding>
<binding name="WSHttpBinding_IServiceClass" />
</wsDualHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:8101/WCFService" binding="wsHttpBinding"
bindingConfiguration="WSHttpBinding_IServiceClass" contract="TCP.IServiceClass"
name="WSHttpBinding_IServiceClass">
</endpoint>
</client>
</system.serviceModel>
But since I added a reference using TCP Binding endpoint,
I expected :
address=net.tcp://localhost:8100/WCFService
and binding="mexTcpBinding"
The Service is working but I would like to know, What's going on here.
What is the reason for this. Is it due to the baseAddress or some preference is given to wsHttpBinding?
Thoughts are appreciated.
Thanks.
The mex binding (short for Metadata EXchange) is not an endpoint which can be used to consume your service. Instead, it's used only used to expose information (or meta information) about all the "real" endpoints of your service - notice that your service class doesn't implement the IMetadataExchange contract which you defined in your TCP/Pipe endpoints.
In your case, your service has only one "real" endpoint - the one using wsHttpBinding, which implements the WCFService.IServiceClass interface. That's why there's only one endpoint in your client configuration.
Now, if you had another endpoint using a non-metadata binding (and not the IMetadataExchange contract), they would show up in the client config as well:
<system.serviceModel>
<services>
<service name="WCFService.ServiceClass" behaviorConfiguration="metaDataSupport">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/WCFService"/>
<add baseAddress="net.tcp://localhost:8100/WCFService"/>
<add baseAddress="http://localhost:8101/WCFService"/>
</baseAddresses>
</host>
<endpoint address="tcpmex"
binding="mexTcpBinding"
contract="IMetadataExchange" />
<endpoint address="namedpipemex"
binding="mexNamedPipeBinding"
contract="IMetadataExchange" />
<endpoint address=""
binding="netNamedPipeBinding"
contract="WCFService.IServiceClass" />
<endpoint address=""
