XML processing

[lwcbdev]

I'm trying to process some XML text but the VB compiler rejects the XML references (i.e. Dim oXMLDoc As Xml.XmlDocument).  I tried adding Imports System.XML but that didn't work and since "Imports System" is already there the first references should work.  I have checked the code in Visual Studio (creating my own FakeKidat class to intercept that code) and it works.

What are the KiDAT Visual Studio dependencies and/or what .Net Framework is it compiled against?  And/Or how do I get XML to work?
