What is ASP.NET
Techno World and Development Trend
ASP.NET is a technology for building powerful, dynamic Web applications. It is part of the .NET Framework.
Developer Productivity
ASP.NET helps you deliver real world Web applications in record time.
Easy Programming Model ASP.NET makes building real world Web applications dramatically easier. ASP.NET server controls enable an HTML-like style of declarative programming that lets you build great pages with far less code than with classic ASP or technologies like PHP or JSP. Best of all, ASP.NET pages work in all browsers – including Firefox, Opera, Safari, and Internet Explorer.
Great Tool Support A broad range of tools support development with ASP.NET. You can work with a simple text editor (even Notepad), take advantage of the freely available Visual Web Developer 2005 Express Edition, or work with a full-powered integrated development environment, such as Visual Studio 2005. For enterprise developers, Visual Studio Team System 2005 includes additional tools for stress-testing and designing Web applications.
Starter Kits Not sure how to get started building an ASP.NET Web site? Download one of the ASP.NET Starter Kits – ready-built Web sites using best practices to help you see how a site should be created. Starter Kits for personal, club, portal and e-commerce Web sites are already available, and both Microsoft and third parties are making many more available.
Easy to get started Quickly get up to speed programming with ASP.NET by following along with the QuickStart tutorials. Read a guided tour of Visual Web Developer to become familiar with its features. Access the broad and growing community support for ASP.NET.
Improved Design
ASP.NET helps you create appealing, functional Web applications.
Master Pages ASP.NET makes it easy to create and apply a common look-and-feel to your Web site with Master Pages. Change the Master Page, and all pages automatically update to reflect those changes.
Themes Give your Web pages a consistent appearance with the built-in theming support in ASP.NET. Easily organize and apply changes to stylesheets and controls by applying a new theme to your pages.
Built Upon Standards
ASP.NET helps you create pages compliant with international standards.
XHTML Compliance Creating XHTML-compliant pages is easy with ASP.NET. Web controls support rendering valid, well-formed XHTML markup with a simple configuration option.
Accessibility Support Create Web applications usable by the widest possible audience support for building and testing accessible Web applications.
Improved Security
ASP.NET helps you protect your data and users.
Application Services There is no need to write common code for managing users and personalization with ASP.NET, as these features are included as application services. ASP.NET membership services provide best practices guidance and support for managing access to your Web applications.
Built-in Protection ASP.NET provides built-in protection from many common forms of hacker attacks, including cross-site scripting, request-replay attacks and more.
Improved Performance and Scalability
ASP.NET lets you use serve more users with the same hardware.
Caching Caching can dramatically improve the performance of Web applications, and ASP.NET supports many forms of caching. Output caching improves the rendering of controls to XHTML. Database caching enables the application to be notified when the underlying database changes, eliminating unnecessary queries.
Web-Farm Session State ASP.NET session state lets you share session data user-specific state values across all machines in your Web farm. Now a user can hit different servers in the web farm over multiple requests and still have full access to her session.
Extensible Architecture
ASP.NET can grow and change with your needs.
Provider Model The application services of ASP.NET use the provider model to connect to external services for storage and more. This enables the developer to change the database or other service used to store the membership, personalization or site map information by editing the configuration.
Web Parts Easily build portal applications with the built-in Web part functionality. Create Web applications that enable end users to organize and personalize their page content and layout.
