3. Introduction

4. Introduction
ASP.NET is an open source web framework for building modern web apps and services with .NET [Microsoft]
It creates websites based on HTML5, CSS, and JavaScript that are simple, fast, and can scale to millions of users
ASP stands for Active Server Pages [w3schools]
ASP supports many different development models:
Classic ASP
ASP.NET Web Forms
ASP.NET MVC
ASP.NET Web Pages
ASP.NET API
ASP.NET Core

5. Introduction The ASP Technology Classic ASP - Active Server Pages
ASP and ASP.NET are server side technologies
Both technologies enable computer code to be executed by an Internet server
When a browser requests an ASP or ASP.NET file, the ASP engine reads the file, executes any code in the file, and returns the result to the browser
Classic ASP - Active Server Pages
ASP (aka Classic ASP) was introduced in 1998 as Microsoft's first server side scripting language
Classic ASP pages have the file extension .asp and are normally written in VBScript

6. Introduction ASP.NET ASP.NET Web Pages
ASP.NET was released in 2002 as a successor to Classic ASP
ASP.NET pages have the extension .aspx and are normally written in C# (C sharp)
ASP.NET 4.6 is the latest official version of ASP.NET
ASP.NET 5 was expected to be an important redesign of ASP.NET
However, the development of ASP.NET 5 was stopped in favor of ASP.NET Core
ASP.NET Web Pages
ASP.NET Web Pages is an SPA application model (Single Page Application)

7. Introduction ASP.NET MVC ASP.NET Web API
The SPA model is quite similar to PHP and Classic ASP
ASP.NET Web Pages is being merged into the new ASP.NET Core
ASP.NET MVC
ASP.NET MVC is an MVC application model (Model-View-Controller)
ASP.NET MVC is being merged into the new ASP.NET Core
ASP.NET Web API
ASP.NET API is an API application model (Application Programming Interface)
ASP.NET API is being merged into the new ASP.NET Core

8. Introduction ASP.NET Web Forms ASP.NET Core
ASP.NET Web Forms is an event driven application model
ASP.NET Web Forms is not a part of the new ASP.NET Core
ASP.NET Core
ASP.NET Core was released in 2016
ASP.NET Core merges ASP.NET MVC, ASP.NET Web API, and ASP.NET Web Pages into one application framework

9. ASP.NET - First Example

10. ASP.NET - First Example
An ASP.NET page is made up of a number of server controls along with HTML controls, text, and images
Sensitive data from the page and the states of different controls on the page are stored in hidden fields that form the context of that page request
ASP.NET runtime controls the association between a page instance and its state
An ASP.NET page is an object of the Page or inherited
All the controls on the pages are also objects of the related control class
When a page is run, an instance of the object page is created along with all its content controls

11. ASP.NET - First Example
An ASP.NET page is also a server side file saved with the .aspx extension
It is modular in nature and can be divided into the following core sections:
Page Directives
The page directives set up environment for the page to run
directive defines page-specific attributes used by ASP.NET page parser and compiler
Page directives specify how the page should be processed, and which assumptions need to be taken about the page
It allows importing namespaces, loading assemblies, and registering new controls with custom tag names and namespace prefixes

12. ASP.NET - First Example Code Section
The code section provides the handlers for the page and control events along with other functions required
We mentioned that, ASP.NET follows an object model
Now, these objects raise events when some events take place on the user interface, like a user clicks a button or moves the cursor
The kind of response these events need to reciprocate is coded in the event handler functions
The event handlers are nothing but functions bound to the controls
The code section or the code behind file provides all these event handler routines, and other functions used by the developer

13. ASP.NET - First Example Page Layout
The page layout provides the interface of the page & contains the server controls, text, JavaScript, and HTML tags

14. Master Pages in ASP.NET

15. Master Pages in ASP.NET
ASP.NET master pages allow you to create a consistent layout for the pages in your application
A single master page defines the look and feel and standard behavior that you want for all of the pages (or a group of pages) in your application
You can then create individual content pages that contain the content you want to display
When users request the content pages, they merge with the master page to produce output that combines the layout of the master page with the content from the content page
