Introduction to ASP.NET
- 1. ASP.NET Presented By Rajkumar Soy CSE 4th year 1252510908
- 2. Evolution of web development • Standards such as HTML (Hypertext Markup Language) and XML (Extensible Markup Language) were created. • Need to develop languages and programming tools that could integrate with the Web.
- 3. The Early Web Development World • Separate, tiny applications that are executed by server-side calls -CGI (Common Gateway Interface) • Scripts that are interpreted by a server-side resource: Classic ASP (Active Server Pages)
- 4. What’s Wrong with Classic ASP • Classic ASP is a solid tool for developing web applications using Microsoft technologies. • Length Code • No IDE (integrated development environment) for developers • ASP Code is interpreted.
- 5. .NET Framework • The .NET framework is a software development framework from Microsoft. It provides a controlled programming environment where software can be developed, installed and executed on Windows-based operating systems. • The .NET languages: These include Visual Basic, C#, JScript .NET (a server-side version of JavaScript), J# (a Java clone), and C++.
- 6. ASP.NET • ASP.NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic websites, web applications and web services. • ASP.NET gives you the ability to code in any supported .NET language (including Visual Basic, C#, J#, and many other languages that have third-party compilers).
- 7. How does ASP.NET work? • ASP.NET applications are executed via a sequence of HTTP requests and HTTP responses. • Client Web browser request ASPX pages. • IIS passes the request to the ASP.NET engine on the server. • The Web server executes the ASPX page and produce XHTML + CSS + JavaScript • ASP.NET file is returned to the browser as plain HTML
- 8. Visual Studio as ASP.NET development tool • Visual Studio is a development tool, which provides a rich environment where you can rapidly create advanced applications. • Some of the features of Visual Studio include the following: -Page design -Automatic error detection -Debugging tools -IntelliSense
- 9. Visual Studio a web development tool
- 10. ASP.NET development models • ASP.NET supports three different development models: -Web Pages -Web Forms and - MVC (Model View Controller)
- 11. Web Pages (Single Pages Model) Web Pages is the simplest programming model for developing ASP.NET web pages. It provides an easy way to combine HTML, CSS, JavaScript and server code. • Easy to learn, understand, and use • Built around single web pages • Similar to PHP and Classic ASP • Server scripting with Visual Basic or C# • Full HTML, CSS, and JavaScript control
- 12. Web Page in Visual Studio
- 13. Web Forms (Event Driven Model) • Web Forms is the oldest ASP.NET programming model, with event driven web pages written as a combination of HTML, server controls, and server code. • Web Forms are compiled and executed on the server, which generates the HTML that displays the web pages. • Web Forms comes with hundreds of different web controls and web components to build user-driven web sites with data access.
- 14. Web Form in Visual Studio
- 15. MVC (Model View Controller) MVC is a framework for building web applications using a MVC (Model View Controller) design: • The Model represents the application core • The View displays the data • The Controller handles the input The MVC model also provides full control over HTML, CSS, and JavaScript.
- 16. MVC Model
- 17. MVC Controller
- 18. MVC View
- 19. Advantages of ASP.NET • Advantage • ASP.NET drastically reduces the amount of code required to build large applications. • The ASP.NET framework is complemented by a rich toolbox and designer in the Visual Studio integrated development environment. WYSIWYG editing, drag-and-drop server controls, and automatic deployment are just a few of the features this powerful tool provides. • Being language-independent, it allows you to choose the language that best applies to your application or partition your application across many languages. • ASP.NET makes for easy deployment. There is no need to register components because the configuration information is built-in.
- 20. Disadvantage of ASP.NET • As ASP.NET uses .NET framework which works on windows platform so the websites can build only in windows platform not other platform like linux ,macintosh, solaris etc.
