ASP.NET 2.0 Features
Introduction to ASP.NET 2.0
With the release of ASP.NET 1.0, Microsoft revolutionized web application
development by providing a rich set of features aimed at increasing the
productivity of developers. Now with ASP.NET 2.0, Microsoft has raised the bar
to a much higher level by providing excellent out-of-thebox features that are
not only geared toward increasing the productivity of developers but also
toward simplifying the administration and management of ASP.NET 2.0
applications. These new features, combined with the increased speed and
performance of ASP.NET 2.0, arm developers with a powerful platform that can
make a significant impact on the way web applications are developed, deployed,
and maintained.
This chapter takes a quick tour of the new ASP.NET 2.0 features. Specifically,
this chapter will discuss the features of this new, improved platform that will
help you in designing, developing, and deploying enterprise-class web
applications.
ASP.NET 2.0 Features
If you have worked with ASP.NET 1.x versions, you will undoubtedly agree that it
was a great product that provided huge improvements in the way web applications
were designed and deployed. If ASP.NET 1.x was a great product, then what’s
wrong with it? Well, nothing, actually, but when developing software, there is
always a trade-off between how much can be done, how many resources you have,
and how much time you have to do it. There is an almost never-ending supply of
features you can add, but at some stage you have to ship the product. You
cannot doubt that ASP.NET 1.0 shipped with an impressive array of features, but
the ASP.NET team members are ambitious, and they not only had plans of their
own but also listened to their users. ASP.NET 2.0 addresses the areas that both
the development team and users wanted to improve. The aims of the new version
are:
-
Reduce the number of lines of code required by 70%: The
declarative programming model freed developers from having to write reams of
code, but there are still many scenarios where this cannot be avoided. Data
access is a great example, where the same Connection, DataAdapter/DataSet, and
Command/DataReader code is used regularly.
-
Increase developer productivity: This partly relates to
reducing the amount of code required, but is also affected by more server
controls encompassing complex functionality, as well as providing better
solutions for common web site scenarios (such as portals and personalized
sites).
-
Provide the fastest web server platform: Although ASP.NET
1.x offered a fast server platform, ASP.NET 2.0 will improve areas such as
application start-up times and provide better application tracing and
performance data. Innovative caching features will enhance application
performance, especially when SQL Server is used.
-
Support for mobile development: In ASP.NET 1.0, the
Microsoft Mobile Internet Toolkit (MMIT in version 1.0 and ASP.NET Mobile
Controls in version 1.1) provided this support, including separate controls for
building web pages suitable for small screen browsers. In ASP.NET 2.0, the MMIT
is no longer required because mobile support is built into all controls. This
reduces the amount of code required, as well as the need for specialist
knowledge about mobile platforms.
-
Provide the best hosting solution: With the large number
of Internet applications being hosted, it’s important to provide better
solutions for hosters. For example, better management features to identify and
stop rogue applications will give hosters more control over their current
environment. More control can also be given to hosted companies by use of the
new web-based administration tool, allowing users to easily control the
configuration of applications remotely.
-
Provide easier and more sophisticated management features:
Administration of ASP.NET applications under version 1.x required manual
editing of the XML configuration file, which is not a great solution for
administrators. Version 2.0 brings a graphical user interface–based
administration tool that is integrated with the Internet Information Services
(IIS) administration tool.
-
Easy implementation of entire scenarios: The better management
features are built on top of a management application programming interface
(API), allowing custom administration programs to be created. Along with
application packaging, this will provide support for easily deployable
applications, with or without source.
Even from this broad set of aims, you can see that ASP.NET 2.0 is a great
advance from 1.x for both developers and administrators. For the purposes of
this chapter, the features of ASP.NET 2.0 based on the following three core
themes are examined:
-
Developer productivity
-
Administration and management
-
Speed and performance
Note that this chapter isn’t an in-depth look at any specific feature—instead it
gives you a taste of what’s to come so that you can see how much easier web
development is going to be.
