ASP.Net - Skin Your Web Apps Using Model-View-Controller

Article describes and provides samples for the very obvious feature of ASP.NET: considering that the axpx.vb code behind exists and also the vb classed defined, we can change the aspx “skin” of the application that way we want, not only as style / css, but as layout, too. We can even replace the entire aspx with another or even load them dynamically as long as some rules get respected.
