With this new newsletter framework available, the next step,
as you see illustrated in the .NET framework, is to create controls to consume
them. That is out of scope of this article, but needs to be mentioned.
Because we know the abstract interface, a control could utilize whatever
functions it needs, and works only by dragging/dropping with minimal impact on
the user and a great amount of time saved to the developer. This is a very
powerful feature that I hope to write about in the future.
