Microsoft's ASP.net is a server-side scripting technology that can be used to create dynamic and interactive Web applications. An ASP.net page is an HTML page that contains server-side scripts that are processed by a web server before being sent to the user’s browser. You can combine ASP with Extensible Markup Language (XML) and Hypertext Markup Language (HTML) to create powerful interactive Web sites. ASP.net coding is more "compact" than ASP code; the scripts required to perform a given function are shorter in ASP.net than they are in ASP.
Since the server-side script is building a regular HTML page, it can be served to almost any browser. An ASP.net file can be created by using any text editing tool, such as notepad.
