With Version 2.0 of the SOAP Toolkit Microsoft will be adding full support for the Web Services Description Language and SOAP 1.1.
Microsoft is also announcing that version 2.0 will be fully supported by Microsoft product support, unlike version 1.0, which is an MSDN sample application.
In upgrading from version 1 to version 2 of the SOAP Toolkit, Microsoft has responded to customer requests to make some architectural changes to the product.
