I'm trying to use the Custom Class Web Service template as an example and 
learning tool (need to create a WS somewhat like it) - but the code 
created by Web Matrix has lots of compilation errors - although I now 
recognize that some of the code is C#!. It also uses methods that are new 
to me so I'm really struggling to get it to work. I've managed to get a 
compilable version in VB that makes sense to me but now get exceptions on 
execution like "System.InvalidOperationException: The type OrderDetails 
was not expected. Use the XmlInclude or SoapInclude attribute to specify 
types that are not known statically." - whatever that means!!! Help, 
anyone?!! Is there a "pure" VB version of it that works or can someone 
tell me how to get it running? Thanks!
