Summary:
The article has explored the properties and methods of the SoapEnvelope Class in WSE2.0's Microsoft.Web.Services2 namespace. The codes can be used for reference, and they can be copied and pasted while testing. Since SoapHeader is treated differently in the Visual Studio IDE, a class was designed to incorporate this information.
The SoapHeader code was tested using the SopHdr.asmx file, but the information in the header can be passed to the web service via client applications. In fact, web service authentication can be carried out incorporating the credentials in the SoapHeader [Reference: Professional ASP.NET Web Services, Russ Bassiura et al, Wrox Press, ISBN: 1-861005-45-8, 2001].
