What is ASP.NET ?

ASP.NET is an open-source server-side Web application framework designed for Web development to produce dynamic Web pages. It was developed by Microsoft to allow programmers to build dynamic web sites, web applications and web services 

ASP.NET works on top of the HTTP protocol, and uses the HTTP commands and policies to set a browser-to-server bilateral communication and cooperation

ASP.NET consists of a large number of controls such as text boxes, buttons, and labels for assembling, configuring, and manipulating code to create HTML page.


The ASP.NET application codes can be written in any of the following languages:
     • C# (C Sharp)
     •  Visual Basic.Net
     • Jscript
     •  J#

The three flavors of ASP.NET:

Web Forms
MVC (Model view Controller)
Web Pages


ASP.NET Web Forms are:
• Based on Microsoft ASP.NET technology, in which code that runs on the server dynamically generates Web page output to the browser or client device.
• Compatible with any browser or mobile device. An ASP.NET Web page automatically renders the correct browser-compliant HTML for features such as styles, layout, and so on.
• Compatible with any language supported by the .NET common language runtime, such as Microsoft Visual Basic and Microsoft Visual C#.
• Built on the Microsoft .NET Framework. This provides all the benefits of the framework, including a managed environment, type safety, and inheritance.
• Flexible because you can add user-created and third party controls to them.

The MVC Programming Model

MVC is one of three ASP.NET programming models.
MVC is a framework for building web applications using a MVC (Model View Controller) design:
• The Model represents the application core (for instance a list of database            records).
• The View displays the data (the database records).
• The Controller handles the input (to the database records).

   The MVC model also provides full control over HTML, CSS, and JavaScript.

The MVC model defines web 
applications with 3 logic layers:

The business layer (Model logic)
The display layer (View logic)

The input control (Controller logic)

ASP.NET Web Pages is a framework that you can use to create dynamic web pages. A simple HTML web page is static; its content is determined by the fixed HTML markup that's in the page. Dynamic pages like those you create with ASP.NET Web Pages let you create the page content on the fly, by using code
