The service works fine on test server, but on the production ser

Answer 1

had the same problem. i fixed it by adding httpsGetEnabled to serviceBehaviors>behavior like this:

<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>

maybe it helps someone else. dont think that u need this hint after 4years =)

Answer 2

I know that answer it's so late but I had the same problem and the solution was:

Add tags [ServiceContract] and [OperationContract] on interface that it is implemented on service .svc. Visual Studio create interface when you select WCF Service but I deleted the interface and I created my own interface.

[ServiceContract]
public interface IService1
{
    [OperationContract]
    void DoWork();
}

I hope to help somebody.

Yes the issue is with publishing metadata. Just adding one more tips. You can also add service meta data using code, like this :

ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;

host.Description.Behaviors.Add(smb);

Answer 4

You basically need three things to enable browsing to your WSDL for a WCF service:

1. a service behavior which enables service metadata
2. set the httpGetEnabled=True on that service metadata behavior to allow http browsing to that metadata
3. a mex endpoint on your service

So your config on the server side might looks something like this (plus a bit more stuff):

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MetadataBehavior">
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>

    <services>
      <service behaviorConfiguration="MetadataBehavior" name="YourService">
        <endpoint address="" 
                  binding="basicHttpBinding" 
                  contract="IYourService" />
        <endpoint address="mex" 
                  binding="mexHttpBinding" 
                  contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>

Points 1 and 2 are handled by this line here:

<serviceMetadata httpGetEnabled="true" />

You need to reference that service behavior in your <service> tag for it to become active.

Point 3 (MEX endpoint) is this section here:

<endpoint address="mex" 
          binding="mexHttpBinding" 
          contract="IMetadataExchange" />

For http, use the mexHttpBinding, and the IMetadataExchange contract is a WCF system contract for metadata exchange .
