I want to enable WSDL retrieval for a webservice that I created. I can 'call' the webservice through the .svc file that I made:
http://localhost/test.svc
<%# ServiceHost Language="C#" Debug="true" Service="Project.MyService" CodeBehind="MyService.svc.cs" %>
Calling the page gives the standard .NET message saying "Metadata publishing for this service is currently disabled." with instructions to enable publishing.
I followed instructions and added the web.config entries, however calling http://localhost/test.svc?wsdl produces the same result... How can I enable WSDL publishing for my webservice?
web.config entries
<service name="Project.IMyService" behaviorConfiguration="MyServiceTypeBehaviors" >
<endpoint contract="IMetadataExchange" binding="mexHttpBinding"
address="mex"
/>
<host>
<baseAddresses>
<add baseAddress="http://localhost/test.svc"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
Sounds crazy but just remove behaviorConfiguration="MyServiceTypeBehaviors" from the service definition andlet the behavior anonymous (with no name). It will remain
<services>
<service name="WcfServiceLibrary1.IMyService" >
<endpoint contract="IMetadataExchange" binding="mexHttpBinding"
address="mex"
/>
<host>
<baseAddresses>
<add baseAddress="http://localhost/test.svc"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior >
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
The mex endpoint and httpGetEnabled look ok. This link covers the topic in some more detail and may be of use.

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" />
<endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange" />
<!--<endpoint address="mexHttp" binding="mexHttpBinding" contract="IMetadataExchange" />-->
<host>
<baseAddresses>
<!--<add baseAddress="net.tcp://localhost:6666/WCFNetTcpService/"/>-->
<add baseAddress="net.tcp://localhost:808/WCFNetTcp/WCFNetTcpService.svc" />

</baseAddresses>
</host>
</service>

<baseAddressPrefixFilters>
<add prefix="net.tcp://localhost:808"/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>
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 trying to create a WCF service, but the metadata doesn't appear, i try:
<system.serviceModel>
<services>
<service
name ="MyNamespace.IMyContract"
behaviorConfiguration="mex">
<endpoint
address = ""
binding = "wsHttpBinding"
contract = "MyNamespace.IMyContract"
/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="mex">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
I try to access with http://MyServer/receptor.svc but shows that Metadata publishing for this service is currently disabled. and http://MyServer/mex shows 404, why? What am i doing wrong?
OBS1: i publish my service in IIS7.5 on Windows 7.
OBS2: if i remove behaviorConfiguration="mex" the metadata works, but with basicHttpBinding not with wsHttpBinding.
I forget to put:
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
I am deploying a WCF Service to IIS 7 and when I navigate to the service URL I get a page like this:
I do not get the typical landing page like this (copied from the web just to show example, data blurred to protect the innocent):
Can someone tell me what I am doing wrong? The service works as expected but there is nothing for a user of this service to view to know what the methods are or where to get the WSDL.
Here are my relevant files:
App.Config (in service project and copied to service site as Web.Config for IIS)

I also tried using 'webHttpBinding' instead of 'wsHttpBinding' and it didn't seem to make a difference.
ServiceHost Service="MyService.MyService" ... is this line correct?
How can I use IMetadataExchange endpoint to get information about service metadata?
Do I need to implement it in a class like we do for other interfaces ?
Please help me ...
The framework will take care of the implementation for you.
However, you must create a service behavior that enables this.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<!-- behavior that enables metadata exchanges -->
<behavior name="mexGet">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<!-- assign the custom behavior here -->
<service name="MyNamespace.MyImplementation"
behaviorConfiguration="mexGet">
<host>
<baseAddresses>
<add baseAddress="http://localhost:3849"/>
</baseAddresses>
</host>
<endpoint
address="MyService"
binding="wsHttpBinding"
contract="MyNamespace.MyServiceInterface"
>
</endpoint>
<endpoint
address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange">
</endpoint>
</service>
</services>
</system.serviceModel>
</configuration>
No, just add the endpoint that exposes IMetadataExchange. You don't have to implement anything.
No need to implement 'IMetadataExchange'. Just add endpoint:
<endpoint
address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
One important thing, you must declare serviceMetadata, or your IMetadataExchange will not be found:
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
I'm wanting to get a WCF-over-TCP service working. I was having some problems with modifying my own project, so I thought I'd start with the "base" WCF template included in VS2008.
Here is the initial WCF App.config and when I run the service the WCF Test Client can work with it fine:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
<services>
<service name="WcfTcpTest.Service1" behaviorConfiguration="WcfTcpTest.Service1Behavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8731/Design_Time_Addresses/WcfTcpTest/Service1/" />
</baseAddresses>
</host>
<endpoint address="" binding="wsHttpBinding" contract="WcfTcpTest.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WcfTcpTest.Service1Behavior">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
This works perfectly, no issues at all.
I figured changing it from HTTP to TCP would be trivial: change the bindings to their TCP equivalents and remove the httpGetEnabled serviceMetadata element:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
<services>
<service name="WcfTcpTest.Service1" behaviorConfiguration="WcfTcpTest.Service1Behavior">
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:1337/Service1/" />
</baseAddresses>
</host>
<endpoint address="" binding="netTcpBinding" contract="WcfTcpTest.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WcfTcpTest.Service1Behavior">
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
But when I run this I get this error in the WCF Service Host:
System.InvalidOperationException: The contract name 'IMetadataExchange' could not be found in the list of contracts implemented by the service Service1. Add a ServiceMetadataBehavior to the configuration file or to the ServiceHost directly to enable support for this contract.
I get the feeling that you can't send metadata using TCP, but that's the case why is there a mexTcpBinding option?
Well, if you want to have metadata - TCP or HTTP - you still need to include the serviceMetadata behavior!
<behaviors>
<serviceBehaviors>
<behavior name="WcfTcpTest.Service1Behavior">
<serviceDebug includeExceptionDetailInFaults="True" />
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
Sure, you can't have a "HttpGetEnabled" on it - but the behavior itself must be present in order to enable exchange of metadata (and thus the IMetadataExchange contract).
