ASP .NET supports full of Visual Basic, not VBScript.

ASP .NET supports C# (C sharp) and C++.

ASP .NET uses new ADO .NET.

ASP .NET supports JScript as before.

ASP .NET contains a large set of HTML controls and 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 validation controls and programmable list boxes.

A new data grid control supports sorting, data paging, and everything that you expect from a dataset control.

All ASP .NET objects on a Web page that can expose events that can be processed by ASP .NET code.

Load, Click and Change events handled by code makes coding much better and much simpler organized.

ASP .NET components are heavily based on XML and like the new AD Rotator, that uses XML to store advertisement information and configuration.

ASP .NET supports forms-based user authentication, including automatic redirecting and cookie management of unauthorized logins.

ASP .NET allows for user accounts and roles, to give each user (with a given role) access to different executables and server code.

ASP .NET also provides greater scalability.

To scale an application over several servers,server to server communication has been greatly enhanced.One example of this is the ability to run XSL transformations ,XML parsers,and even resource hungry session objects on other servers.

The first request for an ASP .NET page on the server will compile the ASP .NET code and keep a cached copy in memory and the result of this is greatly increased performance.

Configuration of ASP .NET is done with plain text files and configuration files can be uploaded or changed while the application is running. No need to restart the server and no more metabase or registry puzzle.

No more server restart to replace or deploy compiled code. ASP .NET simply redirects all new requests to the new code.

ASP .NET is not fully compatible with earlier versions of ASP, so most of the old ASP code will need some changes to run under ASP .NET and to overcome this problem, ASP .NET uses a new file extension ".aspx". This will make ASP .NET applications able to run side by side with standard ASP applications on the same server.
