ASP.NET has better language support, a large set of new controls, XML-based components, and
better user authentication.
ASP.NET provides increased performance by running compiled code.
ASP.NET code is not fully backward compatible with ASP.
ASP.NET uses ADO.NET.
ASP.NET supports full Visual Basic, not VBScript.
ASP.NET supports C# (C sharp) and C++.
ASP.NET supports JScript.
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 can expect from a
All ASP.NET objects on a Web page can expose events that can be processed by ASP.NET code.
Load, Click and Change events handled by code makes coding much simpler and much better
ASP.NET components are heavily based on XML. Like the new AD Rotator, that uses XML to store
advertisement information and configuration.
ASP.NET supports form-based user authentication, cookie management, and automatic redirecting of
ASP.NET allows user accounts and roles, to give each user (with a given role) access to different
server code and executables.
Much was done with ASP.NET to provide greater scalability.
Server-to-server communication was greatly enhanced, making it possible to scale an application
over several servers. One example of this is the ability to run XML parsers, XSL transformations
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. The result of this is greatly increased performance.
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.
No more server-restart to deploy or replace 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.
To overcome this problem, ASP.NET uses a new file extension ".htmlx". This will make
ASP.NET applications able to run side by side with standard ASP applications on the same
