Get Started with ASP.NET
ASP.NET is a technology for building powerful, dynamic Web applications and is part of the .NET Framework.
ASP.NET helps you deliver real world Web applications in record time. To see this in action, watch this video to see how easy it is to build a cross-browser Ajax-enabled web task list application from scratch using ASP.NET 2.0, Atlas, and the free Visual Web Developer development tool.
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. There are a number of Webcasts available to show you how you can migrate your skills to ASP.NET.
Starter kits 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.
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.
ASP.NET helps you create appealing, functional Web applications.
design 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. See this video for more information on Master Pages.
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. See this video for more information on the Theme support in ASP.NET.
Built Upon Standards
ASP.NET helps you create pages compliant with international standards.
Creating XHTML-compliant pages is easy with ASP.NET. Web controls support rendering valid, well-formed XHTML markup with a simple configuration option. This article provides an overview of why creating XHTML markup is important, and how ASP.NET makes it easy.
Create Web applications usable by the widest possible audience support for building and testing accessible Web applications. See this article for more information on accessibility support in ASP.NET.
ASP.NET helps you protect your data and users.
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. Watch this video for more information on adding membership and personalization features to your Web applications.
ASP.NET provides built-in protection from many common forms of hacker attacks, including cross-site scripting, request-replay attacks and more. See this article for more information on common exploits, and how you can protect your Web applications using ASP.NET.
Improved Performance and Scalability
ASP.NET lets you use serve more users with the same hardware.
Visual Web Developer 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. See this video for more information on ASP.NET's caching support.
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. See this article for more information on configuring ASP.NET session state.
ASP.NET can grow and change with your needs.
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. This article series showcases how you can extend ASP.NET via the provider model.
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. This video shows how you take advantage of Web parts to create highly customizable Web pagehttp://asp.net/getstarted/default.aspx?tabid=61
It may have been part of something else you use.
Before deleting it, first disable it in your start menu and see what effects it has on any programs or web browsing.
I suggest getting Startup instpector to use for this purpose. It is easier to use, less chance of making mistakes as it ties the listed ap to the program that is originating it.
Get Startup Monitor while you're there too. It notifies you whan any ap (like Realplayer, etc, tries to load itself into the start menu and requires your permission for it to be loaded to autostart.
Spybot and msconfig can be used to do this too, but the small (and free ap, Startup monitor) is easier to use and is not as prone yo your making mistakes.
