One question: why does it never return true? (Look at botom of image, addresses are the same!)

An endpoint configuration section for contract 'xxx' could not be loaded because more than one end



I'm trying to test calling a webservice, I've found several free ones on http://webserviceshare.com, but none of them work for me.  Some of them give example calling code in C# which I've translated to VB.NET, they're typically just two to four lines, I don't think I've translated them incorrectly.

On that I've tried is US Zip Validator.  I added a Service Reference to http://www.webservicemart.com/uszip.asmx?WSDL, called ZipService.

I then call it like so:

            Dim myZipService As ZipService.USZipSoapClient = New ZipService.USZipSoapClient()
            Dim myCity As String = myZipService.ValidateZip("27707")

I get the following error on the first line of code:

"An endpoint configuration section for contract 'ZipService.USZipSoap' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name."

A page with information on this web service (including C# source code) is at:


Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap



I created 2 projects in my solution:

  1. Classic asp.net web service (asmx)
  2. Class library project which references service
  3. web site project which references class library project
  4. Windows app project which references service.

Both projects were created in 3.5 framework and in Visual Studio 2008 Beta 2.

I added web service reference to Class library project. When it asked for namespace I typed "CurrencyProxy". Projects build ok, but when I run web app, Class library throws an error: Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap' 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 contract could be found in the client element.

I believe it has something to do with app.config in Class library project. Here is part from app.config:

<binding name="CurrencyServiceSoap" closeTimeout=

WCF EndPoint Tracking


How can i check that which Endpoint is calling WCF Service.

How to add default endpoint to ServiceHost for metadata?

Hi there, I was looking into default endpoints and they seem nice. But how do I add such an endpoint for MetadataExchange? I thought it'd be something like the following pasted code, but it doesn't work. Get all sorts of errors, like no address set or "IMetadataExchange isn't known contract, add behavior". Now I do now how to add the correct behavior and such, but I thought the default endpoint could do this? Type serviceType = typeof(EmailValidator); Uri serviceUri = new Uri("http://localhost:8080/"); ServiceHost host = new ServiceHost(serviceType, serviceUri); host.AddDefaultEndpoints(); host.AddServiceEndpoint(new ServiceMetadataEndpoint()); host.Open();Dennis van der Stelt http://bloggingabout.net/blogs/dennis/ http://twitter.com/dvdstelt/

The service cannot be started. This service has no endpoint defined....But it has!?!

Hi Foks,I'm following this tutorial on how to create RESTful services in WCF:http://www.codemeit.com/wcf/wcf-restful-pox-json-and-soap-coexist.htmlI would like to test the created service using the WCF Default Test Client, but when I run the application (F5) the service does not start and I get this message:"The service cannot be started. This service has no endpoint defined. Please add at least one endpoint for the service in config file and try again."However I do have endpoints defined for this service..I also have two other services running in the same application, which work fine:This is the relevant portion of my app.config:<behaviors>              <serviceBehaviors>                        <behavior name="WCF_Lib_Default.Service1Behavior">                   <serviceMetadata httpGetEnabled="True"/>                   <serviceDebug includeExceptionDetailInFaults="False" />             &nbs

Can I write a wcf endpoint to communicate with JSON from Jquery on page?

Hi Guys,I need to be able to expose information to a page, and I need to write the information in xml on my webserver which will be dynamically created from the database. I need to use json to pass the data from the screen back to the server two way communication xms back and forth. Is it actually any good using a wcf endpoint to serve the json back to the page and use query with wcf? Is this possible?Or is it easier to use standard pages .aspx and just do a call to a url and get the json with jquery....We will probably want to send this information to other locations at some point in the future too....Cheers,Pete

Error when creating a net.tcp endpoint in wcf

I am trying to create a simple wcf service that has a net.tcp endpoint.  My OS is Vista and I am hosting the service in IIS 7.  I have set my default website binding for net.tcp to "9200:*" and added net.Tcp to my Enabled Protocols in my website hosting the service and the default website.  Here is my Config Values:   <system.serviceModel>     <services>       <service name="FirstWcfService.Service" behaviorConfiguration="ServiceBehavior">         <!-- Service Endpoints -->         <endpoint address="" binding="netTcpBinding" contract="FirstWcfService.IService"             bindingConfiguration="tcpbinding"/>         <endpoint address="mextcp" binding="mexTcpBinding" contract="IMetadataExchange"/>         <endpoint address="" binding="wsHttpBinding" contract="FirstWcfService.IService"             />         <endpoint address="mexhttp" binding="mexHttpBinding" contract="IMetadataExchange"/>       </service>     </services>     <behaviors>       <serviceBehaviors>         <behavior name="ServiceBehavior">           <!-- To receive exception details in faults for debugging purposes,                set the value below to true.  Set to false befor

How to set and map a Method in the Service file with endpoint elements and binding elements

Hi all, I have created a service file like OSService.svc in that i have two methods like one is FileUpload and FileDownload for e.g :- [WebInvoke(UriTemplate = "/fileupload/{fileName}" , Method = "POST" )]         [OperationContract]         void FileUpload(string fileName, Stream fileContents); same as Filedownload also. People you may know these methods are inside the interface of service file what you are using i'e i have created a interface as IOSService.cs. So, what i need now is i want to write separate endpoint for FileUpload and Filedownload.Because i want to set separate value for receiveTimeout  and openTimeout for the Fileupload and FileDownload process in binding section in the web.config file itself. The below code was i'm using right now but still i'm not able to the set separate value of endpoint elements in the bindings. EndPoint Section:- <endpoint name = "endPoint1"  address  = "localhost:8000/OSService.svc/" bindingConfiguration = "TransactionalTCP"   binding  = "netTcpBinding"          contract = "IOSService"/> Binding Section:-  <binding name = "TransactionalTCP"  transactionFlow = "true"   /&

Calling one endpoint from another endpoint in the same service

Hi, I have a WCF service host Im hosting in IIS that defines a few services and one of those services has a number of endpoints. The endpoints that belong to the same service are there to let me specify different contracts and they all use the same binding and behaviour. For the most part it works fine until a specific situation occurs: The service gets stuck when one of the endpoints tries to make a call to another endpoint in the same service. Consider the following example: <service behaviorConfiguration="GeneralServiceBehavior" name="Base"> <endpoint address="/Addresses" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="CommonObjects.IAddresss" /> <endpoint address="/Attachments" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="CommonObjects.IAttachments" /> </service> In the example above if a call is made from IAttachments implementor back to this service to access the IAddress endpoint I get stuck in what seems to be a deadlock until I get a timeout on the calling thread and then I see the call come through to the IAddress endpoint, but at that point its already too late as the channel is closed. I have looked at the InstanceContext and ConcurrencyMode. This particular servic

Incorrect hostname in EndPoint location in WSDL for a service with multiple bindings and with multip

We have a WCF web service that is exposed through multiple bindings.  The site is  accessed through multiple IP Addresses/Hostnames (internet/intranet).  Some of the bindings use http transport while others use https transport. The web application is configured to use .NET 4.0 with multipleSiteBindingsEnabled="true" so that we shouldn't have problems with multiple ip addresses/hostnames. What we see is that when the WSDL is accessed using a http based URL (external), the hostnames in the endpoint addresses for http transport based bindings in WSDL are correct (ie, they use the hostname header from the request) while the hostnames in the endpoint addresses for https transport based bindings in the WSDL are incorrect (ie, they do not use the hostname header in the request - they seem to use the hostname from the first available binding in IIS for that scheme and end up with the local machine names/ip addresses in the URL).   We could work around by setting the external hostname/ip in the first binding in IIS for the respective scheme, but then WSDLs accessed from intranet clients would have wrong URLS now. This happens the other way around as well, ie, when the WSDL is accessed using https, the https based addresses are fine, but http addresses in the WSDL are not correct. It looks like hostname header is used only for WSDL endpoint addre

Debugger endpoint configuration

When I started my current project, I was relatively new and followed the default WCF template closely as a result.  For a while I was running it in the Visual Studio debugger, which allowed me to develop the WCF service without having to worry about deployment.  As such, I never really had to deal with web.config.Then I got to the point where I tried deploying it, and things got messy.  Long story short, I tried hosting it in a windows service, ran into some problems with regards to endpoint configuration, and had to mess around with web.config quite a bit.  After some learning I decided it would be best to do a rollback to before I had even created the windows service, and start again with a fresh windows service.I've removed the windows service and its installer from my solution, and I decided to try and run the WCF service in the debugger.  However, this did not work, and I got an error page stating the following:  No protocol binding matches the given address ''. Protocol bindings are configured at the Site level in IIS or WAS configuration. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.  Exception Details: System.InvalidOperationException: No protocol binding matches the given address 'h

EndpointNotFoundException - No endpoint listening

Hi all: I created and hosted a test WCF service on my development server.  I beleive IIS is configured properly because I can get to the IIS page from any browser off the network.  When I build my simple client application, I can successfully add the service reference, however when I execute the function, I get the following error: There was no endpoint listening at http://[domain name]/TestService2/Service1.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. Unfortuantely, I am not using a normal domain name, but an IP address only:  http://##.##.##.##/TestService2/Service1.svc below is a portion of my webconfig:  <system.serviceModel>   <services>    <service name="WcfService1.Service1" behaviorConfiguration="WcfService1.Service1Behavior">     <endpoint address="" binding="wsHttpBinding" contract="WcfService1.IService1">      <identity>       <dns value="" />      </identity>     </endpoint>     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExch

WCF : How to prevent an endpoint from being published in the service WSDL?

Suppose I have a WCF service which has 2 endpoints A and B. I want to enable mex/wsdl on this service but my requirement is that B should not be published in the WSDL. So to say B is only for internal purpose and clients should never be aware of it. Is there a way (most probably somehow using IWsdlExporterExtension), to remove this endpoint B from being published in the metadata?

WCF endpoint couldnt found for HTTPS

Can't Add Service Reference in VS 2010 to a net.tcp endpoint

I've got a service running (well, it doesn't crash), but when I try to add a Service Reference to it, I keep getting Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:55555/mex'. Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:55555/mex'. If the service is defined in the current solution, try building the solution and adding the service reference again. The pertinent parts of my config file are:   <netTcpBinding> <binding name="ReliableDuplexBinding" closeTimeout="00:00:10" openTimeout="00:00:10" receiveTimeout="00:00:30" sendTimeout="00:00:15" maxBufferPoolSize="1048576" maxBufferSize="262144" maxReceivedMessageSize="262144"> <readerQuotas maxDepth="33" maxStringContentLength="100000" maxArrayLength="131072" maxBytesPerRead="262144" maxNameTableCharCount="54000" /> <reliableSession inactivityTimeout="05:00:00" enabled="true" /> <security mode="None"> <transport> <extendedProtectionPolicy policyEnforcement="Never" /> </transport> </security> </binding> </netTcpBinding> <behaviors> <serviceBehaviors> <behavior nam
