|
ASP.NET is the latest version of Microsoft's Active Server Pages technology (ASP). |
|
ASP.NET is a web application framework developed by Microsoft to allow programmers to build dynamic web sites, web applications and web services. |
|
ASP.NET is a server side scripting technology that enables scripts (embedded in web pages) to be executed by an Internet server.
|
|
It provides increased performance by running compiled code.
|
|
ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language.
|
|
It has better language support, a large set of new controls and XML based components, and better user authentication.
|
|
ASP.NET makes building real world Web applications dramatically easier. The server controls in ASP.NET enable an HTML-like style of declarative programming that let you build great pages with far less code than with classic ASP. Displaying data, validating user input, and uploading files are all amazingly easy. Best of all, ASP.NET pages work in all browsers -- including Netscape, Opera, AOL, and Internet Explorer.
|
|
ASP.NET pages, known officially as "web forms", are the main building block for application development.
|
|
ASP.NET 2.0 Web Parts can provide a consistent look for a site, while still allowing user customization of style and content.
|
|
ASP.NET 2.0 also provides pre-compilation. An entire web site can be pre-compiled. This provides an easy way to deploy (upload to a server) compiled applications, and because only compiled files are deployed, the source code is protected.
|
|
VS.NET also provides integrated support for debugging and deploying ASP.NET Web applications.

Language Support |
| |
+ |
ASP.NET uses the new ADO.NET. |
+ |
ASP.NET supports full Visual Basic, C# & J# and also JavaScript. |
|
| |
ASP.NET Controls |
| |
+ |
ASP.NET contains a large set of HTML controls. Almost all HTML elements on a page can be defined as ASP.NET control objects that can be controlled by scripts. |
+ |
ASP.NET also contains a new set of object oriented input controls, like programmable list boxes and validation controls. |
+ |
A new data grid control supports sorting, data paging, and everything you expect from a dataset as well as a data table. |
|
| |
ASP.NET Components |
| |
+ |
ASP.NET components are heavily based on XML. Like the new AD Rotator, that uses XML to store advertisement information and configuration |
|
| |
User Authentication |
| |
+ |
ASP.NET supports forms-based user authentication, including cookie management and automatic redirecting of unauthorized logins. |
|
| |
High Scalability |
| |
+ |
Server to server communication has been greatly enhanced, making it possible to scale an application over several servers. |
|
| |
Easy Configuration |
| |
+ |
Configuration of ASP.NET is done with plain text files. |
+ |
Configuration files can be uploaded or changed while the application is running. No need to restart the server. No more metabase or registry puzzle. |
|
| |
Easy Deployment |
| |
+ |
No need to restart the server to deploy or replace compiled code. ASP.NET simply redirects all new requests to the new code. |
