Declaration of an IDO extension class for an IDO

When declaring an IDO extension class, you can add the optional IDOExtensionClass attribute, in order to facilitate adding the necessary IDO metadata to associate an extension class with an IDO. This sample code shows how to associate an extension class with the SLJobMats IDO.

[IDOExtensionClass("SLJobtMats")] 
public class SLJobtMats : IDOExtensionClass 
{ 
   // ...Implementation goes here... 
} 

It is generally a good idea to import some common framework namespaces to make your code less verbose and more clear, and to enable the Explicit and Strict VB compiler options.
