>All in all I just wanted to know your (MS official) opinion to the sentense "...dated technology..." and some others inconsistencies (see my earlier post, but mainly to the dated thing) but it seems that MS is walking around like a cat near the hot porridge in this case study.

If you read the case study, the context of that refers to using VB 6 combined with the SOAP Toolkit. Using the XML Web services classes in the .NET Framework is more modern technology than using VB 6 with the SOAP toolkit.
