ASP.NET programming
ASP.NET is a new programming framework from Microsoft
for developing next generation web Applications. It is a
framework built on the Common Language Runtime and
introduces a new paradigm to server-side Web development
There are several advantages that ASP.NET offers, such
as:
Performance: The code written in ASP.NET is compiled, so
straight ahead it is a performance boost. The code
written in .Net Framework is complied in Common Language
Runtime. ASP.NET can take advantage of early binding,
just-in-time compilation, automatic resource
optimization, runtime profiling, automatic memory
management, enhanced exception handling, and caching
services, right out-of-the-box, this improves the
performance before you start coding. A problem with Web
site’s performance is with data-access. For example, a
database table will spend the majority of its execution
time connecting to the database and querying the
information.
ASP.NET comes with a data-caching module. This
data-caching module allows you to specify what data on
an ASP page to cache and on what conditions to empty the
cache and re-query the data-store.
ASP.NET ships with Performance Counters which system
administrators can use to gather application metrics.
They can be used to measure the performance of either a
single instance of an ASP.NET application or all ASP.NET
applications combined on a computer
Tool
Support : Now you can drag-and-drop web controls like you do VB
controls, double-click and write the server code for the
control. ASP .NET supports XCOPY deployment that requires no
registration or stopping of the server, supports dynamic DLL
updates and extensible configuration using XML files.
Flexibility.
Because ASP.NET is based on the Common Language Runtime, the
power and flexibility of that entire platform is made available
to web application developers. The Common Language Runtime's
Base Class libraries, Messaging, and Data Access solutions are
all seamlessly accessible from the web. ASP.NET is also
language-independent, so you can choose a language that best
applies to your application, or partition your application
across many languages. Further, Common Language Runtime
interoperability guarantees that your existing investment in
COM-based development is preserved when migrating to ASP.NET.
ASP.NET
currently offers built-in support for three languages, C#
(pronounced "C Sharp"), Visual Basic, and JScript.
ASP.NET
is different from ASP in two major ways:
- ASP.NET
offers several programmatic enhancements over ASP, such as,
Compiled ASP.NET Scripts, Caching: Post-Back Forms: Server
Controls, and Deployment.
- ASP.NET
offers a change in programming fundamentals. ASP followed
procedural pattern of creating pages.(e.g.; lets take a form
which takes user information and then authenticates the user.
Here we would generally create a form, which receives the user
information in the first page, and then in the second page we
would process the user collection for authentication in ASP.)
