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 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 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=""
binding="netTcpBinding"
contract="WCFService.IServiceClass" />
<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 a standalone WCF service running on a server behind a firewall. It currently uses wsDualHttpBinding as the service utilizes callbacks. The client works fine in a LAN environment. We have opened the firewall to allow traffic on a custom port and so the discovery of the service now works from outside LAN.
Due to the nature of wsDualHttpBinding this obviously cannot work if the client is behind a firewall of its own. So naturally, netTcpBinding comes to mind which should solve the bidirectional problem. But the strange thing is that when service configuration XML is updated to include netTcpBinding on the same port (and/or exclude wsDualHttpBinding), then even the service discovery no longer works.
I am wondering if there is anything else that I am missing. I have followed the exact advice for configuration from How to: Use netTcpBinding with Windows Authentication and Message Security in WCF Calling from Windows Forms and from Windows Communication Foundation QuickStart - Multiple Binding VS2010.
The configuration:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBindingEndpointConfig">
<security mode="Message" />
</binding>
</netTcpBinding>
</bindings>
<services>
<service name="Service1.Service1.Service">
<endpoint address="Service1" binding="wsDualHttpBinding" contract="Service1.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
<endpoint address="" binding="netTcpBinding"
bindingConfiguration="NetTcpBindingEndpointConfig"
name="NetTcpBindingEndpoint" contract="Service1.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:9999/Service1.Service1/"/>
<add baseAddress="net.tcp://localhost:9999/Service1.Service1/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- 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="True"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
If you can use only single port and you must use netTcpBinding try to configure your service this way:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBindingEndpointConfig">
<security mode="Message" />
</binding>
</netTcpBinding>
</bindings>
<services>
<service name="Service1.Service1.Service">
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>
<endpoint address="" binding="netTcpBinding"
bindingConfiguration="NetTcpBindingEndpointConfig"
name="NetTcpBindingEndpoint" contract="Service1.IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:9999/Service1.Service1/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="False"/>
<serviceDebug includeExceptionDetailInFaults="True"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
When adding service reference try to use this address:
net.tcp://localhost:9999/Service1.Service1/mex
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).
I have two Services called TemplateService, TemplateReportService (both defined in one WCF Service Library) to be exposed to the client application.
And, I am trying to host these services under Windows Service.
Can anyone please guide me if App.config in Windows Service will be same as the one in WCF Library?
Here is my app.config in WCF Library:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
<services>
<service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior"
name="ReportingComponentLibrary.TemplateService">
<endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateService" >
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" ></endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateService/" />
</baseAddresses>
</host>
</service>
<service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior"
name="ReportingComponentLibrary.TemplateReportService">
<endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateReportService" >
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateReportService/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ReportingComponentLibrary.TemplateServiceBehavior">
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="True" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
So, the App.config in my Windows Service(Where I am hosting above two services)
will be same as above or there are only some particular sections that I need to move.
Please guide.
Thank you!
First, remove the as we talked about in your other question. Second libraries don't have their own .config files and there is no (built in) way to import certain configuration sections in .NET. So you must consolidate the configuration settings for each library into the single app.config of the Windows service.
