WCF - convert HTTP to Named Pipe - wcf

Guys I've been looking at a ton of blogs, SO posts this week and I am still unsure as to how I convert my WCF service from HTTP bindings to using Named Pipes.
I think there are different ways to do it, but I am using the web.configs and using a service reference in my code.
Rather than detail everything here I've tried, can I ask this question?
What are the steps I need to take to go from HTTP Binding to Named Pipes?
Do I need this MEX thing I see mentioned in (some) blogs/SO posts?
I know I need to set IIS to enabled protocols: net.pipe... and that IIS Express doesn't support this (that took an afternoon!)
Some relevant code, what I have right now:
in IEmployeeData:
namespace Mobile.ServiceLayer {
[ServiceContract]
public interface IEmployeeData
{ ... }
Calling the WCF service:
string endpointConfigName = "BasicHttpBinding_IEmployeeData";
EmployeeSvcRef.EmployeeDataClient edc = new EmployeeSvcRef.EmployeeDataClient(endpointConfigName);
EmployeeSvcRef.EmployeeListResponse emp = edc.EmployeeList();
WCF service web.config:
<services>
<service name="Mobile.ServiceLayer.EmployeeData">
<host>
<baseAddresses>
<add baseAddress="http://localhost:62734/EmployeeData" />
</baseAddresses>
</host>
</service>
...
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false before deployment -->
<serviceMetadata httpGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
client web.config:
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IEmployeeData" />
...
<client>
<endpoint address="http://localhost:62734/EmployeeData.svc" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IEmployeeData" contract="EmployeeSvcRef.IEmployeeData"
name="BasicHttpBinding_IEmployeeData" />
Like I said I've looked at SO posts and blogs but there's always a piece of the puzzle missing it seems!
EDIT: Client web.config after wizard:
<endpoint address="net.pipe://localhost/EmployeeData.svc/" binding="netNamedPipeBinding"
bindingConfiguration="NewBinding0" contract="IEmployeeData"
name="" kind="" endpointConfiguration="">
<identity>
<certificateReference storeName="My" storeLocation="LocalMachine"
x509FindType="FindBySubjectDistinguishedName" />
</identity>
</endpoint>

Ok this is what I did. You may find it easier to use the built-in tools mentioned in Max's comments. Right click on a web.config and choose Edit WCF Configuration. Get the WCF service done first and, providing the endpoints are set up, running this on the client (right click it's web.config) will present you with a wizard.
SERVER WEB.CONFIG
Service name is the fully-qualified name of the interface e.g. Mobile.ServiceLayer.IEmployeeData
The base address changes to
net.pipe://localhost/EmployeeData.svc
. Notice the port number is removed and the .svc is present(!)
Create an endpoint, the contract being your interface and binding of type netNamedPipeBinding.
Add a second endpoint for MEX which is MetadataEXchange.
Set ServiceMetaData httpGetEnabled to false.
<system.serviceModel>
<services>
<service name="Mobile.ServiceLayer.IEmployeeData">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/EmployeeData.svc" />
</baseAddresses>
</host>
<!-- NetPipe -->
<endpoint
address=""
binding="netNamedPipeBinding"
contract="IEmployeeData" name="MyNetPipe" />
<!-- Mex (Net.Tcp / Net.Pipe ) -->
<endpoint name="EmployeeDataNetPipeMex" address="mex" binding="mexNamedPipeBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
CLIENT WEB.CONFIG
Remove the binding entry from 'basicHttpBinding'
Add the section with an entry named NetNamedPipeBinding_IEmployeeData
Inside 'client' add an endpoint with the address
net.pipe://localhost/EmployeeData.svc
the contract being the 'referencename'.'interface'
<bindings>
<basicHttpBinding>
</basicHttpBinding>
<netNamedPipeBinding>
<binding name="NetNamedPipeBinding_IEmployeeData" />
</netNamedPipeBinding>
</bindings>
<client>
<endpoint address="net.pipe://localhost/EmployeeData.svc" binding="netNamedPipeBinding"
bindingConfiguration="NetNamedPipeBinding_IEmployeeData" contract="EmployeeSvcRef.IEmployeeData"
name="NetNamedPipeBinding_IEmployeeData" />
</client>

Can't host tcp based wcf service on IIS, Cannot obtain Metadata from net.tcp://localhost/TestApp2/MyService error pops up

I have a simple test purpose WCF service. I'm trying to host it under IIS 7.5 ( Windows 7 ) but no luck so far. I'm getting error
Cannot obtain Metadata from net.tcp://localhost/TestApp2/MyService
I have a web site TestApp2 under Default Web Site, I enabled tcp on Default Web Site and TestApp2. Here is my web.config file, while I realize that this error simply states that I didn't have endpoint for metadata exchange, I can't see what's the problem because I included endpoint for metadata exchange.
<system.serviceModel>
<services>
<service behaviorConfiguration="ServiceBehavior" name="MyService">
<endpoint address="net.tcp://localhost/TestApp2/MyService"
binding="netTcpBinding"
bindingConfiguration="PortSharingBinding"

<endpoint address="MEX"
binding="mexTcpBinding"
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost/TestApp2/MyService" />
</baseAddresses>
</host>
</service>

Thanks.
My guess is your service isn't actually called MyService but rather it is in a namespace. This means your declared endpoints are not getting picked up, and the default ones (which doesn't include IMetadataExchange) are being used instead.
Add the name of your namespace to the attribute in the config and it should work.

WCF - Can't Generate Metadata/Implement MEX for NetMsmq Binding under IIS WAS?

I have been successfull in implementing NetTcp bindings and metadata under WAS but I am having a problem with the netMsmqBinding under WAS/IIS. In a nutshell, I can implement MEX for a Self Hosted NetMsmq binding application but not WAS/IIS. It seems like WAS is rejecting any of the addresses that I use where I can use any address in the self hosted app. In other words I can do this in self hosted:
<system.serviceModel>
<services>
<service name="Microsoft.Samples.MSMQTransactedSample.OrderProcessorService" behaviorConfiguration="OrderProcessorServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/ServiceModelSamples/service" />
</baseAddresses>
</host>
<!-- Define NetMsmqEndpoint -->
<endpoint address="net.msmq://localhost/private/ServiceModelSamplesTransacted" binding="netMsmqBinding" bindingConfiguration="TransactedBinding" contract="Microsoft.Samples.MSMQTransactedSample.IOrderProcessor" />
<!-- the mex endpoint is exposed at http://localhost:8000/ServiceModelSamples/service/mex -->
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="OrderProcessorServiceBehavior">
<serviceMetadata httpGetEnabled="True" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<netMsmqBinding>
<binding name="TransactedBinding">
<security mode="None" />
</binding>
</netMsmqBinding>
</bindings>
</system.serviceModel>
Hoever, when I try something similar in WAS, it says no endpoint lisening at address 8000. It won't host the metdata. Can someone help me get metadata or implement MEX for NetMsmq in WAS:
<system.serviceModel>
<bindings>
<netMsmqBinding>
<binding name="MsmqBindingNonTransactionalNoSecurity" exactlyOnce="false">
<security mode="None"/>
</binding>
</netMsmqBinding>
</bindings>
<services>
<service name="Portal.LoadSim.Services.MsmqService" behaviorConfiguration="PortalServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/PortalLoadSimServices10/MsmqService"/>
</baseAddresses>
</host>
<!-- Define NetMsmqEndpoint -->
<endpoint address="net.msmq://localhost/private/PortalLoadSimServices10/MsmqService.svc" binding="netMsmqBinding" bindingConfiguration="MsmqBindingNonTransactionalNoSecurity" contract="Portal.LoadSim.Shared.IMsmqService" />
<!-- the mex endpoint is exposed at http://localhost:8000/PortalLoadSimServices10/MsmqService/mex -->
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="PortalServiceBehavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
You need to add URL access control for your services. This command should work for you:
netsh http add urlacl url=http://localhost:8000/PortalLoadSimServices10/MsmqService user="NT AUTHORITY\NetworkService" listen=yes
To delete the entry
delete urlacl url=http://localhost:8000/PortalLoadSimServices10/MsmqService
HTH
UPDATE: This is not the anwer to your problem. This is what you would do if you wanted to run the services as a self-hosted application and run it under non-standard account. Sorry I was getting it mixed up. I tried using your configuration on a sample application at home and found I had to do two things to get it to work - one, I have to rename the queue to the path and name of the svc file (e.g. PortalLoadSimServices10/MsmqService.svc) and rather than using the base address just browse to the svc file in your IIS host application. You might also need to modify the queue permissions so iis can access it correctly. Let me know if this solves your issue.

WCF service not accessible in Windows Server 2008

I recently built a WCF Service, and now I'm deploying it to Windows Server 2008. Right now, we don't have secure protocol turned on. But we will. I'd like to get it working either way. In the site, I've had Anonymous authentication enabled as well as Forms authentication. The reason I did this was to prevent the authentication popup on the iPad, Android and Internet Explorer. So now they just get to the Login screen. Oh and I did activate WCF in Windows features. If you're also knowledgeable about making this https ready, I'd also like to figure that out. Thanks!!
I'm getting this error when I try pasting in the *.svc PATH into the URL.
System.ServiceModel.ServiceActivationException:
The service
'/WCFServices/Accessioning/QuickDataEntryService.svc'

Here is my web.config configuration thus far.

I have no clue what caused the exception above, but here was the final verdict. There were a lot of things required for WCF and using an SSL certificate (HTTPS protocol). Pardon the formatting.. I don't like how Stack Overflow sometimes puts the code into a block and sometimes it doesn't.
The following were required for the web.config on HTTPS:
Here are some places that required the "requireSSL" attribute:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" timeout="30" protection="All" requireSSL="true" />
</authentication>
<httpCookies httpOnlyCookies="false" requireSSL="true" domain="" />
Notice the "s" in "httsGetEnabled" below:
<behaviors>
<endpointBehaviors>
<behavior name="AspNetAjaxBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceMetadata httpsGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
Bindings (missing in non-SSL web.config):
<bindings>
<webHttpBinding>
<binding name="webBinding">
<security mode="Transport">
</security>
</binding>
</webHttpBinding>
</bindings>
Services (notice the "s" in "mexHttpsBinding"):
<services>
<service behaviorConfiguration="ServiceBehavior" name="A.LIMS.UI.Web.WCFServices.Accessioning.QuickDataEntryService">
<endpoint behaviorConfiguration="AspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="webBinding" contract="A.LIMS.UI.Web.WCFServices.Accessioning.QuickDataEntryService" />
<endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />
</service>
</services>
Last but not least. I'm not using .NET 4.0, but I did try .NET on a different machine. With .NET 4.0 I couldn't get the WCF services to work without having this configured to the actual URL being used. If there were two domains for the same IP, WCF only worked with the domain in this block inside the system.ServiceModel XML block in the web.config. I did not test https in the .NET 4.0, so I'm assuming the protocol on the URL would be https below:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<baseAddressPrefixFilters>
<add prefix="http://subdomain.domain.com/" />
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
Oh, I also had to turn on WCF on the Windows Server 2008 box. And it required a server reboot!

Changing WCF service to require SSL

I have a WCF service which was running fine on a http binding. I've tried to update this to use SSL but i am getting the following error:
"Could not find a base address that matches scheme http for the endpoint with binding WSHttpBinding. Registered base address schemes are [https]."
This only occurs when i set the site to "Require SSL" in IIS 7.5 if I uncheck it it works fine.
Here's my config
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior" >
<dataContractSerializer maxItemsInObjectGraph="2147483646"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->

</behavior>
</serviceBehaviors>
</behaviors>
<bindings>

</wsHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="ServiceBehavior" name="WcfService1.Service1">

<endpoint address="mex" binding="mexHttpsBinding" bindingConfiguration=""
name="MexHttpsBindingEndpoint" contract="IMetadataExchange" />
</service>
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
I've tried allsorts and nothing seems to get me there, any help is greatly appreciated!
Modify your binding configuration:
<bindings>
<wsHttpBinding>
<binding name="wsHttpEndpointBinding">
<security mode="Transport" />
</binding>
</wsHttpBinding>
</bindings>
And reference that configuration in your endpoint by setting its bindingConfiguration attribute to the name of configuration.
<endpoint address="" binding="wsHttpBinding"
bindingConfiguration="wsHttpEndpointBinding"
name="wsHttpEndpoint" contract="WcfService1.IService1" />
You can also delete the host section with base address because it is not used when hosting in IIS.
In addition to changing the binding configuration settings (as Ladislav mentioned)... Change HTTP in the base address to HTTPS.

Configuration binding extension could not be found

I am trying to get a WCF webservice running which will participate in distributed transactions. I keep getting the following error message...
Configuration binding extension 'system.serviceModel/bindings/myBinding' could not be found. Verify that this binding extension is properly registered in system.serviceModel/extensions/bindingExtensions and that it is spelled correctly
Here is the web.config
<system.serviceModel>

<service name = "DistServiceX">
<endpoint

</service>
</services>

Can anyone see what is wrong with this? It's driving me crazy!
Thanks

You are referring to a custom binding here:
<service name = "DistServiceX">
<endpoint
address=""
binding="myBinding"
contract="IDistService" />
However, there is no custom binding called myBinding anywhere in your config.
I assume you really want to refer to a wsHttpBinding and the myBinding binding configuration that you specified in your config file. Furthermore: the name of the service must match the fully qualified name of the class that implements the service - including namespace (and also: the name of the contract being implemented by that service and exposed on a given endpoint must include any namespaces):
<service name="YourNamespace.DistServiceX">
<endpoint
address=""
binding="wsHttpBinding"
bindingConfiguration="myBinding"
contract="YourNamespace.IDistService" />
