NGWS frameworks is an object-oriented system. When using specific parts of the frameworks, you need to include references to the namespace in code, and when building your application, to the Dynamic Link Library (DLL) that contains the namespace.
When using ADO+ from either Visual Basic 7.0 or C#, you must reference the System.Data namespace, as well as either System.Data.ADO or System.Data.SQL, depending on which Managed Provider you choose to use. For example, to access data using the SQL Managed Provider, in Visual Basic you would use:
Imports System.Data Imports System.Data.SQL
In C#:
using System.Data; using System.Data.SQL;
