Adding C# Soap Header to a client that calls BT2010 Orchestration published as a WCF Web Service

Question

I've added code from this reference to my orchestration (that is published as a WCF webservice):
Accessing SOAP Headers in Orchestrations.
I have a C# client that I was previously using before I was using any of the SOAP Headers.  I've been looking at dozens of blogs, and find the answers to anything related to SOAP Headers most confusing (and often specific to unique cases). 
I'm using BT2010.  How can I add username, password, and a custom header called "ApplicationID" to my existing C# program and pass it to the orchestration/web service?
Thanks,
Neal

Neal,
The BizTalk WCF Service Publishing Wizard does not include custom SOAP header definitions in the generated metadata. To publish metadata for WCF services using custom SOAP headers, you should manually create a Web Services Description Language (WSDL) file.
You can use the externalMetadataLocation attribute of the
<serviceMetadata> element in the Web.config file that the wizard generates to specify the location of the WSDL file. The WSDL file is returned to the user in response to WSDL and metadata exchange (MEX) requests instead of the auto-generated WSDL.
The following XML data shows an example of a part of the WSDL file defining custom SOAP headers:
<wsdl:operation name="Request">
<soap12:operation soapAction="http://Microsoft.Samples.BizTalk.NetTcpAdapter/OrderProcess/IOrderProcess/Request" style="document" />
<wsdl:input name="Order">
<soap12:header message="i0:Order_Headers" part="SalesAgent" use="literal" />
<soap12:body use="literal" />
</wsdl:input>
<wsdl:output name="OrderConfirmation">
<soap12:header message="i0:OrderConfirmation_Headers" part="PaymentAgent" use="literal" />
<soap12:body use="literal" />
</wsdl:output>
</wsdl:operation>
