The CustomBinding on the ServiceEndpoint with contract 'IService1' lacks a TransportBindingElement error when trying to access wcf service

Question

I am trying to access WCF service. But its giving me following error:

The CustomBinding on the ServiceEndpoint with contract 'IService1' lacks a TransportBindingElement. Every binding must have at least one binding element that derives from TransportBindingElement.

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: The CustomBinding on the ServiceEndpoint with contract 'IService1' lacks a TransportBindingElement. Every binding must have at least one binding element that derives from TransportBindingElement.

Following is my service model full config:

<system.serviceModel>

As you can see it already has the Transport Element. But still I am getting above error. What is the reason?

My Client Config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>

    <bindings>
      <wsHttpBinding>
        <binding name="CustomBinding_IService1" />
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://subdomain.domain.com/service1.svc" binding="wsHttpBinding"
        bindingConfiguration="CustomBinding_IService1" contract="ServiceReference1.IService1"
        name="CustomBinding_IService1">
        <identity>
          <userPrincipalName value="DOMAIN\subdomaindomaincom_web" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>

seems good to me, try to make some arbitrary changes (remove security, remove some other tags) to see if maybe some tag is problematic — Yaron Naveh, Aug 23 '13 at 14:00
shouldn't it be bindingConfiguration="Wrabind", not bindingName="Wrabind" — Alex, Aug 23 '13 at 14:03
thanks @voo its working now. I removed the `name` attribute and added `bindingConfiguration` attribute and it worked. Add it as your answer. — Aishwarya Shiva, Aug 23 '13 at 15:34
@YaronNaveh I tried voo's suggestion and the problem is solved. But I am getting the previous error again i.e. MessageSecurityException as I asked in previous question that you answered. I am updating my this question with client config. Can you please change it and add maxClockSkew as I done on Server config? I don't know how to do that on client side. — Aishwarya Shiva, Aug 23 '13 at 15:37
not sure what config you refer to, just add localClientSettings as in the example or via QCF config editor — Yaron Naveh, Aug 23 '13 at 17:06
but where to add it in app.config at client side? that's what I am asking. — Aishwarya Shiva, Aug 23 '13 at 17:27

Man, I advice you not to do like that. If you use Custom binding on your server, you should use it in your client also. If you use WSHttp on client, your server should have the same binding enpoint. I doubt that you need to create custom binding in your case. In 90% of cases the standart WCF binding would be enought to make a proper solution. Don't develop a new bicycle. As for your second problem, suppose it is the reason of using WSSecurity11WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10 in your custom binding, which requires to use certificate for security purposes. Anyway I recommend you to change the custom binding with the WSHttp

Actually I was having this http://stackoverflow.com/questions/18400608/how-to-make-wcf-service-server-client-time-difference-independent problem, so I switched to customBinding – Aishwarya Shiva Aug 23 '13 at 19:19
Oh, I see that in your case custom binding is a way to go. But is possible to synchronize the clock on server and client? And does you message security exception states same thing as before? – Alex Aug 23 '13 at 21:05
ya it states the same thing. Also the time synchronisation can't help. Since those who will install my application might have more time difference then MaxClockSkew, as my application will be downloaded worldwide, so this will restrict them to use my application. That I don't want. I am trying to figure out its solution since two weeks. I am out of options now. Please help. – Aishwarya Shiva Aug 23 '13 at 21:11
@AishwaryaShiva It is hard to simulate your problem, so I can only advice you the following. Make shure you have the same binding configuration on both server and client. Make sure you set MaxClockSkew on both client and server. Make sure that you set LocalClientSecuritySettings MaxClockSkew on client side, and LocalServiceSecuritySettings MaxClockSkew on server side. If you do everything, as I've said - it should work. See http://msdn.microsoft.com/en-us/library/aa738468.aspx, suppose it could help you – Alex Aug 24 '13 at 18:49
