What is ASP.NET and Why we Use it ?

ASP short for Active Server Pages meaning that they execute on a web server and .NET is a framework developed by Microsoft .

ASP.NET is a Web development framework for building Applications like console based,mobile based ,web pages and web sites etc with HTML, CSS, JavaScript and server scripting,C#,VB.

ASP.NET supports three different development models:

(i)Web Pages :

Asp.Net Web Page is a single page model like classic Asp and Php.It also has no drag and drop server controls, server events and state management techniques.

 Asp.Net Web Page has built-in template and helpers also provide full control over markup.(we can use WebMatrix to develop asp.net web page)

(ii)MVC (Model View Controller) :

3 Components of Web Application by MVC are

•  Models for data , 
• Views for display , 
• Controllers for input. 

It is lightweight, provide full control over markup and support many features that allow fast & agile development. Henec it is best for developing interactive web application with latest web standards.(Visual studio and Visual web developer are tools for developing ASP.NET MVC application)

(iii)Web Forms :

It is an event driven development model meaning , An event is generated (or raised) when "something happens," such as the user pressing a button. Often, events are generated by user action, but events can also be generated by the system starting or finishing work.

 For example, the system might raise an event when a file that you open for reading has been read into memory or when your battery's power is running low.

Asp.Net Web Form has built-in data controls and are best for rapid development with powerful data access.(Visual studio and Visual web developer are tools for developing ASP.NET MVC application).
