WCF Default Endpoint Missing - wcf

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)
<system.web>
<compilation debug="true"/>
</system.web>
<system.serviceModel>
<services>
<service name="MyService.MyService" behaviorConfiguration="Web">
<clear />
<endpoint address=""
binding="wsHttpBinding"
name="ws"
behaviorConfiguration="Web"
contract="MyService.IMyService" />
<!--
<endpoint address=""
behaviorConfiguration="Web"
binding="webHttpBinding"
bindingConfiguration=""
name="web"
contract="MyService.IMyService" />
-->
<host>
<baseAddresses>
<add baseAddress="http://services.mydomain.com/MyService" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="Web">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="False"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="Web">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
MyService.svc
<%# ServiceHost Service="MyService.MyService"
Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
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?

WCF Metadata publishing for this service is currently disabled

I am struggling to display metadata while using WCF.
I have looked all over the place. I'm not sure if it is a setting in my web.config file, or my actual service is not working properly. But I get the "Metadata publishing for this service is currently disabled." page when I debug.
<?xml version="1.0"?>
<configuration>
<system.serviceModel>

<webHttpBinding>
<binding name="myWebHttp"/>
</webHttpBinding>
</bindings>

Your service doesn't have SOAP endpoint so there are no valid metadata to be exposed. You don't need neither serviceMetadata behavior or MEX endpoint if you don't have SOAP service.
Btw. how do you debug the service?

what is the "behaviorConfiguration" attribute of service?

what is the "behaviorConfiguration" attribute of service?
<services>
<service name="WcfServiceNetMSMQ.Service1" behaviorConfiguration="WcfServiceNetMSMQ.Service1Behavior">
<host>
<baseAddresses>
<add baseAddress = "http://localhost:8010/WcfServiceNetMSMQ/Service1/" />
</baseAddresses>
</host>
<endpoint address ="net.msmq://localhost/private/myqueue" binding="netMsmqBinding" contract="WcfServiceNetMSMQ.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
There are 3 important sections when you configure a WCF service.
1) Defining the Services:
<services>
<service behaviorConfiguration="SOAPRESTDemoBehavior" name="SOAPRESTDemo">
<endpoint address="rest" behaviorConfiguration="SOAPRESTDemoEndpointBehavior" binding="webHttpBinding" contract="ISOAPRESTDemo" />
<endpoint address="soap" binding="basicHttpBinding" contract="ISOAPRESTDemo" />
</service>
</services>
NOTE the value of behaviorConfiguration is a reference to a section further on in the config see below...
2) Defining the 'Service Behaviours'
<serviceBehaviors>
<behavior name="SOAPRESTDemoBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
3) Defining the 'Endpoint Behaviours'
<endpointBehaviors>
<behavior name="SOAPRESTDemoEndpointBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
All 3 sections are the basics for what you need to set up a service (although this can be done programatically).
With regard to your question the behaviorConfiguration section relates to point 2 and 3 in my points above. Its where you lay out the sort of actions you want your service to have. for example above I have said that I want to allow MetaData to be published. This will essentially create a WSDL which describes the service.
The full config is here:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<!--Set up the service-->
<services>
<service behaviorConfiguration="SOAPRESTDemoBehavior" name="SOAPRESTDemo">
<endpoint address="rest" behaviorConfiguration="SOAPRESTDemoEndpointBehavior" binding="webHttpBinding" contract="ISOAPRESTDemo" />
<endpoint address="soap" binding="basicHttpBinding" contract="ISOAPRESTDemo" />
</service>
</services>
<!--Define the behaviours-->
<behaviors>
<serviceBehaviors>
<behavior name="SOAPRESTDemoBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="SOAPRESTDemoEndpointBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
It is a reference to another configuration section:
<behaviors>
<serviceBehaviors>
<behavior name="WcfServiceNetMSMQ.Service1Behavior">
</behaviors>
</serviceBehaviors>
</behaviors>
Where this section contains some global configuration for the whole service.
here's an example of it, it carries some properties of the connection of the service.
<serviceBehaviors>
<behavior name="WcfServiceNetMSMQ.Service1Behavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
Notice that the name in this service behavior corresponds to the one you specified earlier.
Hope that helps.
You will get this error with Behavior name is not setup correctly.
The HTML document does not contain Web service discovery information.
Metadata contains a reference that cannot be resolved: 'http://blabla.com/WebService/Processor.svc'.
Content Type application/soap+xml; charset=utf-8 was not supported by service 'http://blabla.com/WebService/Processor.svc'. The client and service bindings may be mismatched.
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
If the service is defined in the current solution, try building the solution and adding the service reference again.

mexTcpBinding in WCF - IMetadataExchange errors

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).

WCF MetaData not working

I have tried several times to have my WCF service expose MetaData. Instead, I keep keeping the exception:
The contract name 'IMetadataExchange'
could not be found in the list of
contracts implemented by the service
SecurityBroker. Add a ServiceMetadataBehavior to the
configuration file or to the
ServiceHost directly to enable support
for this contract.
... when manually browsing to the service using IE.
(I am presuming this is the same reason why my client application isn't able to generate a service reference. Baby steps and all)
And yet my web.config looks okay:
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<behaviors>
<endpointBehaviors>
<behavior name="webHttpEnablingBehaviour">
<webHttp />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="webHttpEnablingBehaviour">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="IWW.MIGTurbo2.WCF.Security.SecurityBroker">
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
<endpoint address=""
binding="webHttpBinding"
bindingConfiguration="default"
contract="IWW.MIGTurbo2.WCF.Security.ISecurityBroker"
behaviorConfiguration="webHttpEnablingBehaviour">
</endpoint>
</service>
</services>
<client />
<bindings>
<webHttpBinding>
<binding name="default" />
</webHttpBinding>
</bindings>
</system.serviceModel>
So I have my IMetadataExchange contract defined with mex fine, and hooked up, as far as I can see. Have I missed something daft?
Edit
My Service definition is shown below, if this is useful:
<%# ServiceHost Language="C#" Debug="true" Service="IWW.MIGTurbo2.WCF.Security.SecurityBroker" Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory" %>
Your config file has the behaviorConfiguration attribute on the "endpoint" element, but you also need it on the "service" element.
I am using NetTcpBinding for all. In my case I was having the same issue and resolved it by adding:
(a) a behaviorConfiguration="" to the mex endpoint
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" behaviourConfiguration="" />
(b) a behaviorConfiguration="mex" to the service definition:
<services>
<service name="AcmeService" behaviorConfiguration="mex">
(c) The behaviour entry
<behaviors>
<serviceBehaviors>
<behaviour name="mex">
<serviceDebug includeExceptionDetailInFaults="false"/>
<serviceMetadata />
</behavior>
</serviceBehaviors>
</behaviors>
