As for .NET versus SOAP Toolkit -- you should use the one that works with your application. If you're using VB.NET, ASP.NET, or C#, then use .NET. If you're using VB 6.0, VBA, or VC++, then you need to use SOAP Toolkit. If you plan to deploy on Win95, you have to use SOAP Toolkit. As an alternative to SOAP Toolkit, you might also try PocketSOAP.
