  1. ASP.net – Mysteries, Myths and Truths By George W. Ponick IV – Nov. 14, 2006

  2. ASP.net History • ASP.net was first released with Visual Studio .Net in 2002. • Version 1.0 was replaced by 1.1 in April 2003. This release coincided with Visual Studio .NET 2003 and Windows Server 2003. • Version 2.0 was released in November of 2005.

  3. ASP.net Overview • ASP.net was created to replace ASP. • ASP stands for Active Server Page. • ASP.net is built around the Common Runtime Language. • ASP.net uses an event-driven GUI programming paradigm instead of a scripting based paradigm.

  4. Web Programming Paradigms(ASP.net vs ASP(and some others)) Scripting Event Based GUI Ability to separate code from presentation layer Many different languages(any .NET) can be used Closely related to Windows form applications, so a similar development style is possible. • No seperation of business logic and presentation layer • Errors are only found at runtime, not compile time. • One language(in general) per app

  5. ASP.net Benefits • Runtime error handling(try, catch) • User defined controls allow for reusable code blocks in libraries • Session state, or data persisting throughout a users session can be saved on the page, or in an SQL server for use in a server farm. • Compiled code for faster execution

  6. Server Platform • Commonly hosted on Windows 2000 Server, or 2003 Server… • In this configuration it uses IIS(Windows’ Web Server)

  7. Server Platform… tricks • Is Windows the only platform? • No! • With the advent of Mono, .NET and ASP.net can be run on multiple platforms • Windows, Linux, Mac(with some issues?) • IIS, Cassini(.net based Web Server), Apache(mod mono), XSP(Mono’s web server)

  8. Live Demo, Questions • Any Questions?
