"MonoRail is a MVC Web Framework inspired by Action Pack.
MonoRail differs from the standard WebForms? way of development as it enforces separation of concerns; controllers just handle application flow, models represent the data, and the view is just concerned about presentation logic. Consequently, you write less code and end up with a more maintainable application."
