Microsoft's standard .aspx Web forms are a fine model for developing Web pages. However, an alternative design pattern has been gaining popularity in the ALT .NET arena for ASP.NET – the ASP.NET Model-View-Controller (MVC) design pattern. Although this method has already been utilized greatly with Java, such as with JavaServer Faces, Struts, and Spring MVC, ASP.NET developers are choosing to mold the standard page architecture for its support for Test Driven Development (TDD), a clear separation of user interface (UI) and presentation logic, and more intuitive Web URLs.
