New in ASP .NET
- It is not fully ASP compatible
- It has better language support
- It has its ownProgrammable controls
- It has event-driven programming
- It has XML-based components
- It has user authentication, with accounts and roles
- It has higher scalability
- It has capability to increased performance - Compiled code
- It has easier configuration and deployment
Language Support
ASP .NET Controls
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.
Event Aware Controls
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
ASP .NET components are heavily based on XML and like the new AD
Rotator, that uses XML to store advertisement information and
configuration.
User Authentication
ASP .NET supports forms-based user authentication, including
automatic redirecting and cookie management of unauthorized
logins.
User Accounts and Roles
ASP .NET allows for user accounts and roles, to give each
user (with a given role) access to different executables and
server code.
High Scalability
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.
Compiled Code
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.
Easy Configuration
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.
Easy Deployment
No more server restart to replace or deploy compiled code.
ASP .NET simply redirects all new requests to the new code.
Compatibility
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.
