Wrong SOAP Action header in request. Why?

Question

I'm trying connecting to the MS CRM Deployment Service from within CRM plugin (i.e. I don't have ability to use app.config configuration file).

The issue is it's really difficult to replace 'configuration magic' with source code.

While I'm using following configuration file (testing locally in console application):

<client>
    <endpoint address="http://server/XRMDeployment/2011/Deployment.svc"
        binding="customBinding" bindingConfiguration="CustomBinding_IDeploymentService"
        contract="DeploymentService.IDeploymentService" name="CustomBinding_IDeploymentService">
        <identity>
            <userPrincipalName value="DOMAIN\DYNAMICS_CRM" />
        </identity>
    </endpoint>

    ...

</client>

Everything is fine, but when I'm trying to replace configuration with code I'm facing with following. In resulting SOAP message instead of expected header:

<a:Action s:mustUnderstand="1" u:Id="_4">http://schemas.microsoft.com/xrm/2011/Contracts/Services/IDeploymentService/Retrieve</a:Action>

I see something strange:

<a:Action s:mustUnderstand="1" u:Id="_4">http://schemas.xmlsoap.org/ws/2005/02/trust/RST/SCT</a:Action>

Does anybody knows how can I override Action Header and which statement in configuration turns WCF magic making everything work?

I think you should use something like following configuration

[ServiceContract(Name = "DeploymentService",
    Namespace = "http://schemas.microsoft.com/xrm/2011/Contracts/Services/")]
public interface IDeploymentService
{
    [OperationContract(Action="uri://<your service URI>/Retrieve")]
    void Retrieve();
}
