Lots of fascinating articles on SOAP here.
Spent time w/ C# and SOAP today. I rewrote this ASP/VB/SOAP example using C#. Wow is .NET way easier than manually writing out an XML packet, making a request, parsing said XML packet using VBScript… plus you get all the obvious .NET implied features like automatic creation of WSDL descriptors and generated SOAP request and response sample packets. I’ll post my refactoring of the above example in C# soon.
