What is ASP.NET?


     ASP.NET, the next version of ASP, is a programming framework used to create enterprise-class Web Applications. These applications are accessible on a global basis leading to effecient information managment. The advantages ASP.NET offers is more than just the next version of ASP.

     ASP.NET is purely server-side technology. ASP.NET code executes on the server before it is sent to the browser. The code that is sent back to the browser is pure HTML and not ASP.NET code. Like client-side scripting, ASP.NET code is similar in a way that it allows you to write your code alongside HTML. Unlike client-side scripting, ASP.NET code is executed on the server and not in the browser. The script that you write alongside your HTML is not sent back to the browser and that prevents others from stealing the code you developed. s for C++ developers.


ASP.NET is a server side scripting technology that enables scripts (embedded in web pages) to be executed by an Internet server.

  • ASP.NET is a Microsoft Technology
  • ASP stands for Active Server Pages
  • ASP.NET is a program that runs inside IIS
  • IIS (Internet Information Services) is Microsoft's Internet server
  • IIS comes as a free component with Windows servers

ASP.NET File Creation:-

  • An ASP.NET file is just the same as an HTML file
  • An ASP.NET file can contain HTML, XML, and scripts
  • Scripts in an ASP.NET file are executed on the server
  • An ASP.NET file has the file extension ".aspx"

Working step of ASP.NET:-

  • When a browser requests an HTML file, the server returns the file
  • When a browser requests an ASP.NET file, IIS passes the request to the ASP.NET engine on the server
  • The ASP.NET engine reads the file, line by line, and executes the scripts in the file
  • Finally, the ASP.NET file is returned to the browser as plain HTML

Software to work with ASP.NET:-
  • Microsoft .NET Framework
