[Mono-list] Windows Forms...wah

[Tum]

That's why MVC would be good.  By implementing it the MVC way, you can
immediately support both styles of programming.
 
Labels, buttons etc will by default construct their own standard models.

I think people who are against MVC don't understand that you can supply
and use default models.
 
With MVC, you could do this:

// Default model is used.

Button button = new Button("Hello World");


_Or_ this:

// User supplied model.

Button button = new Button(new MyButtonModel());


MVC gives you the choice of having both systems.  Currently, Windows
Forms does not use MVC for things like listboxes (not even internally).
That sucks cause even though you can create an MVC wrapper model around
it, you'll still have the problem of the listbox storing your data
twice.  You can't efficiently add MVC to a non-MVC system, but you can
efficiently add non-MVC looking models to an MVC system.
