I agree.

However! Using Refactoring & Refactoring To Patterns, surely one can *add*
the MVC pattern to an existing app that currently doesn't use the MVC
pattern?

|
| You should not have anything other than visual controls on your forms, the
| Controllers should be separate classes, instantiated in code outside of
the
| form.
|
| You will also need to provide a set of wrapper classes that will allow you
| to detect when you set the properties of your business classes, so that
the
| Controller can handle things like an Changing, or Changed event fired from
| the "property".
|
| As to the visual components on the form, if you want to avoid deriving
from
| the existing controls to implement the Observer pattern, these also need
to
| have wrapper classes that implement the Observer pattern and carry out the
| Update method against the enclosed UI control.
|
| You could also just use the data-aware nature of the existing controls to
| replace teh Observer pattern, but write a Controller that catches the
| Validating event of the controls so that you can enforce business rules
when
| leaving an edit control.
|
| IMO, MVC is fairly well implemented, although not obviously, in the new
..NET
| data-aware controls.
