I've configured a WCF Service and I'm using a transparent proxy in another assembly using Channel Factory. The problem I'm facing is: On the constructor of the channel factory, I have to manually specify the endpoint address name for the service to work, when it should find the address by just using the interface of the service. what am I doing wrong here?
Heres the code:
Service Config:
<system.serviceModel>
<services>
<service name="WcfTestService.Service1" behaviorConfiguration= "ServiceBehavior">
<endpoint address="" binding="wsHttpBinding" contract="Contracts.DataContract.IService1">
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="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>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
Proxy Config:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IService1" />
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost/WCFTestService/Service1.svc" binding="wsHttpBinding"
bindingConfiguration="WSHttpBinding_IService1" contract="Contracts.DataContract.IService1"
name="WcfTestService.Service1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</client>
</system.serviceModel>
Proxy that works, specifying endpoint name:
public class Service1Proxy : IService1
{
private IService1 service;
public Service1Proxy() {
service = new ChannelFactory<IService1>("WcfTestService.Service1").CreateChannel();
}
public string GetData(int value)
{
return service.GetData(value);
}
public CompositeType GetDataUsingDataContract(CompositeType composite)
{
return service.GetDataUsingDataContract(composite);
}
}
The proxy that throws an exception:
public class Service1Proxy : IService1
{
private IService1 service;
public Service1Proxy() {
service = new ChannelFactory<IService1>().CreateChannel();
}
public string GetData(int value)
{
return service.GetData(value);
}
public CompositeType GetDataUsingDataContract(CompositeType composite)
{
return service.GetDataUsingDataContract(composite);
}
}
With this last code block, the channel factory throws the following exception:
The Address property on ChannelFactory.Endpoint was null. The ChannelFactory's Endpoint must have a valid Address specified.
I thought it could create the service just by the interface, but that doens't seem to work, I have to specify the endpoint name "WcfTestService.Service1". some co-workers said that it's possible, but none could show me how.
I appreciate any insights.

I'm trying to create a WCF and consume it from another C# class.
I think I'm doing everything right but i Get the error message says Contract name is not familiar.
This is my Web.config code:
<system.serviceModel>
<services>
<service behaviorConfiguration="PNMSoft.Sequence.Invoices.InvoicesBehavior" name="PNMSoft.Sequence.Invoices.Invoices">
<endpoint name="InvoicesEndPoint" address="" binding="wsHttpBinding" contract="PNMSoft.Sequence.Invoices.IInvoices">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="PNMSoft.Sequence.Invoices.InvoicesBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
This is my interface code:
namespace PNMSoft.Sequence.Invoices
{
[ServiceContract]
public interface IInvoices
{
[OperationContract]
void SendInvoicesToCustomer(int wfid, int userID, int type, string mail, DateTime startDate, DateTime endDate, string clientCode);
}
}
This is my code when I try to activate a function from the service:
InvoicesClient client = new InvoicesClient("InvoicesEndPoint");
client.SendInvoicesToCustomer(IWFID, userID2, type2, Mail, DateFrom2, DateTo2, clientCode2);
On the first row I get this error message: "Could not find endpoint element with name 'InvoicesEndPoint' and contract 'Invoices.IInvoices' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.".
This is the config file on my cient's side:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="InvoicesEndPoint" />
</wsHttpBinding>
</bindings>
<client>
<endpoint address="" binding="wsHttpBinding" bindingConfiguration="InvoicesEndPoint" contract="Invoices.IInvoices" name="InvoicesEndPoint">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</client>
</system.serviceModel>
I guess I need to add something to the config file in my client's side. What should I add?
Thank you in advance!
I solved it, I just had to add the endpoint to the client side's config.
I started working with WCF recently, and I'm having a problem that I just don't have a clue how to solve.
I start a WCF Service using Service Host, but when I use the URI in a browser it doesn't show the contract of the service, and it gives an exception when I try to connect to it using a ChannelFactory.
I created the project in Visual Studio 2017, and didn't do anything to the config file, excpet changing the base address. Both the service interface and implementation are in the root project "folder", and I've tried disabling the firewall and even my antivirus, but nothing seems to work.
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>

<services>
<service name="TaskExecutor.Exec">
<endpoint address="" binding="basicHttpBinding" contract="TaskExecutor.IExec">

<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8001/TaskExecutor/Exec/" />
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
</configuration>
Service interface:
namespace TaskExecutor
{
[ServiceContract]
public interface IExec
{
[OperationContract]
void DoWork();
}
}
Service implementation:
namespace TaskExecutor
{
public class Exec : IExec
{
public void DoWork()
{
Console.WriteLine("Doing work.");
}
}
}
Program launching the service:
using (ServiceHost host = new ServiceHost(typeof(Exec)))
{
host.Open();
Console.WriteLine("exec service started at {0}", host.BaseAddresses[0]);
}
Console.WriteLine("Press any key to end...");
Console.ReadLine();
After launching the program display the message:
exec service started at http://localhost:8001/TaskExecutor/Exec/
Press any key to end...
The service client code is the following:
EndpointAddress endpoint = new EndpointAddress("http://localhost:8001/TaskExecutor/Exec/");
BasicHttpBinding binding = new BasicHttpBinding();
ChannelFactory<IExec> channelFactory = new ChannelFactory<IExec>(binding, endpoint);
IExec proxy = channelFactory.CreateChannel();
proxy.DoWork();
And it gives the exception:
System.ServiceModel.EndpointNotFoundException occurred
HResult=0x80131501
Message=There was no endpoint listening at http://localhost:8001/TaskExecutor/Exec/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
Inner Exception 1:
WebException: Unable to connect to the remote server
Inner Exception 2:
SocketException: No connection could be made because the target machine actively refused it
I seriously don't know what to do, and any help would be amazing.
Thank you very much!
You have exposed metadata but didnt bind it to the service.Here's how you have to.
<behaviors>
<serviceBehaviors>
<behavior name="metadadiscovery">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
Now bind the behavior to the service.
<services>
<service name="TaskExecutor.Exec" behaviorConfiguration="metadadiscovery">
<endpoint address="" binding="basicHttpBinding" contract="TaskExecutor.IExec">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8001/TaskExecutor/Exec/" />
</baseAddresses>
</host>
</service>
</services>
Now when you type the address in the browser you should be able to see wsdl.
http://localhost:8001/TaskExecutor/Exec/
So I figured out what was wrong, It was the code starting the service. instead of what I have It should be:
using (ServiceHost host = new ServiceHost(typeof(Exec)))
{
host.Open();
Console.WriteLine("exec service started at {0}", host.BaseAddresses[0]);
Console.WriteLine("Press any key to end...");
Console.ReadLine();
}
I have a classic WCF webservice. Few weeks ago, in order to answer to a client demand, I added Rest management to my webservice.
But, at the beginning of the week, another client said to me its system can only manage XML-RPC. So he needs to connect to my webservice via this protocol.
So I found this : Configuring XML-RPC behavior for IIS-hosted .SVC file?
First, I compiled the Microsoft.Samples.XmlRpc in order to add it to my project. Two Dll appears : Microsoft.Samples.XmlRpc & Microsoft.ServiceModel.XmlRpc
Then, I created a XmlRpcEndpointBehaviorExtension class, the same as the post above :
namespace WsZendesk
{
public class XmlRpcEndpointBehaviorExtension : BehaviorExtensionElement
{
protected override object CreateBehavior()
{
// this comes from Microsoft.Samples.XmlRpc
return new XmlRpcEndpointBehavior();
}
public override Type BehaviorType
{
get { return typeof(XmlRpcEndpointBehavior); }
}
}
}
After, I created my interface for Xml-Rpc :
namespace WsZendesk
{
[ServiceContract]
public interface IWsZendeskRpc
{
[OperationContract(Action = "wszendesk.GetUserIdFromBarcode")]
void GetUserIdFromBarcode(String sXmlIn, out String sXmlOut);
}
}
Finaly, I modified my web.config in order to allow RPC :
<system.serviceModel>
<services>
<service name="WsZendesk.WsZendesk" behaviorConfiguration="WsZendeskServiceBehavior">
<endpoint address="rest" behaviorConfiguration="restfulBehavior"
binding="webHttpBinding" bindingConfiguration="" name="RESTEndPoint"
contract="WsZendesk.IWsZendeskRest" />
<endpoint address="xmlrpc" behaviorConfiguration="xmlRpcBehavior"
binding="webHttpBinding" bindingConfiguration="" name="RPCEndPoint"
contract="WsZendesk.IWsZendeskRpc" />
<endpoint address="" behaviorConfiguration=""
binding="basicHttpBinding" bindingConfiguration="" name="SOAPEndPoint"
contract="WsZendesk.IWsZendesk" />
</service>
</services>
<extensions>
<behaviorExtensions>
<add name="xmlRpc"
type="WsZendesk.XmlRpcEndpointBehaviorElement, WsZendesk" />
</behaviorExtensions>
</extensions>
<behaviors>
<endpointBehaviors>
<behavior name="restfulBehavior">
<webHttp />
</behavior>
<behavior name="xmlRpcBehavior">
<xmlRpc />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="WsZendeskServiceBehavior">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
Visual Studio said he don't know the child element 'xmlRpc'. So, when I try to launch my webservice, the same error appears during the execution.
Anybody can help me to use Xml-Rpc with my existing webservice ?
For information, my project is in C# 4.
It was not this:
<add name="xmlRpc"
type="WsZendesk.XmlRpcEndpointBehaviorElement, WsZendesk" />
But this:
<add name="xmlRpc"
type="WsZendesk.XmlRpcEndpointBehaviorExtension, WsZendesk" />
I have complete exhausted resources on trying to get NetNamedPipeBinding for my WCF Service working. I was able to get the NorthwindService example working found here.
For the NorthwindService example, I have the following:
namespace NorthwindServices
{
public class Customer : ICustomer
{
public string GetCustomerName(int CustomerID)
{
return CustomerID.ToString();
}
}
}
namespace NorthwindServices
{
[ServiceContract]
public interface ICustomer
{
[OperationContract]
string GetCustomerName(int CustomerID);
}
}
And the configuration for the example is the following:
<system.serviceModel>
<services>
<service name="NorthwindServices.Customer"
behaviorConfiguration="ServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/NorthwindServices/Customer"/>
</baseAddresses>
</host>
<!-- Service Endpoints -->
<!-- Unless fully qualified, address is relative to base address supplied above -->
<endpoint address="CustomerService" binding="netNamedPipeBinding" contract="NorthwindServices.ICustomer"/>
<endpoint address="CustomerService/mex" binding="mexNamedPipeBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<!-- To avoid disclosing metadata information,
set the values below to false before deployment -->
<serviceMetadata httpGetEnabled="False" httpsGetEnabled="False"/>
<!-- 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>
I have an IIS Site defined for this with the details below:
So when I go to 'Add Service Reference' I can pull in the reference perfectly fine.
However, when I try to do the same in my actual application, I still cannot seem to figure it out. I am unable to pull in the reference.
The site structure is the following:
The top level site is an MVC site, and there is an "API" virtual directory below it where the service resides that I am trying to expose over NetNamedPipeBinding.
The bindings for the site are the following:
The config for the service I am trying to expose over named pipes is the following:
<system.serviceModel>
<services>
<service name="Site.API.Service.WorkItemQueueService"
behaviorConfiguration="ServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="net.pipe://localhost/WorkItemQueueService"/>
</baseAddresses>
</host>
<endpoint address="QueueService"
binding="netNamedPipeBinding"
contract="Site.API.Service.IWorkItemQueueService"/>
<endpoint address="QueueService/mex"
binding="mexNamedPipeBinding"
contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="false"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="True" aspNetCompatibilityEnabled="True"/>
The service implementation is the same as the customer service above, but obviously renamed to match the configuration above.
When I try to add a service reference, or find the metadata for this, It cannot find it.
IMPORTANT - All of the pre configuration items such as starting the Net Pipe listerner and role service have been completed, hence the NorthwindServices example works.
I have one console app as a hosting for WCF service. Now, I'm going to add another one WCf service for administer purposes. So, here is my code:
[ServiceContract]
public interface IServiceAdmin
{
[OperationContract]
int GetCount();
}
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)]
public class ServiceAdmin : IServiceAdmin
{
public int GetCount()
{
// It's just a stub to go on
return 1;
}
}
Here is excerpt of App.config applied to services:
<serviceBehaviors>
<behavior name="MyService.ServBehavior">
<dataContractSerializer maxItemsInObjectGraph="2147483646"/>
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="MyService.ServBehavior" name="MyService.MyServ">
<endpoint address="MyServ" behaviorConfiguration="" binding="netTcpBinding" contract="MyService.IMyServ" isSystemEndpoint="false" />
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
</service>
<service behaviorConfiguration="MyService.ServBehavior" name="MyService.MyServAdmin">
<endpoint address="MyServ" behaviorConfiguration="" binding="netTcpBinding" contract="MyService.IServiceAdmin" isSystemEndpoint="false" />
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
</service>
And here is how I get services started:
static void Main(string[] args)
{
ServiceHost myserviceHost = new ServiceHost(typeof(MyServ), new Uri("net.tcp://192.168.1.40:8730/"));
myserviceHost.Open();
ServiceHost myAdminHost = new ServiceHost(typeof(AServiceAdmin), new Uri("net.tcp://192.168.1.40:31337/");
myAdminHost.Open();
Console.ReadLine();
}
The issue is that regular service working good (metadata exchanging can provide info on service methods) and another service (which I mentioned at the beginning, administer service) is not working at all.
That is the reason of it?
Thanks in advance!
The issue was in wrong name of service in App.Config. The right line is
<service behaviorConfiguration="MyService.ServBehavior" name="MyService.ServiceAdmin">
