Below is the web.config file I used.

And am confused whether to add the attributes other than name in binding element.

Answer 1

To enable publishing of your metadata for your service GBCService. I added bindingConfiguration equals to WSHttpBinding_ILogging.
<service name="_1C_GBCService.GBCService" behaviorConfiguration="GBCServiceBehavior">
<endpoint address="" bindingConfiguration="WSHttpBinding_ILogging"
binding="wsHttpBinding"
contract="_1C_GBCService.IGBCService" />
<!--Add the following endpoint.Note: your service must have
an http base address to add this endpoint.-->
<endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
</service>
And changed your protocol mapping to wsHttpBinding and scheme to HTTP because that was the binding you are using. And HTTP because your metadata exchange or mex used non-secured mexHttpBinding.
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" />
<protocolMapping>
<add binding="wsHttpBinding" scheme="http" />
</protocolMapping>
