It is not essential to use the standard webforms development model when developing with ASP.NET. Noteworthy frameworks designed for the platform include:

Castle Monorail, an open-source MVC framework with an execution model similar to Ruby on Rails. The framework is commonly used with Castle ActiveRecord, an ORM layer built on NHibernate.
Spring.NET, a port of the Spring framework for Java.
