Developer
Productivity
ASP.NET helps you
deliver real world Web applications in record
time. |
 |
Easy
Programming Model.
ASP.NET makes building real world Web applications dramatically
easier. ASP.NET server controls enable an HTML-like style of declarative
programming that let you build great pages with far less code than
with classic ASP. Displaying data, validating user input, and uploading
files are all amazingly easy. Best of all, ASP.NET pages work in
all browsers -- including Netscape, Opera, AOL, and Internet Explorer. |
|
Flexible
Language Options .
ASP.NET lets you leverage your current programming language skills.
Unlike classic ASP, which supports only interpreted VBScript and
JScript, ASP.NET now supports more than 25 .NET languages (including
built-in support for VB.NET, C#, and JScript.NET -- no tool required),
giving you unprecendented flexibility in your choice of language. |
|
Great
Tool Support.
You can harness the full power of ASP.NET using any text editor
-- even Notepad! But Visual Studio .NET adds the productivity of
Visual Basic-style development to the Web. Now you can visually
design ASP.NET Web Forms using familiar drag-drop-doubleclick techniques,
and enjoy full-fledged code support including statement completion
and color-coding. VS.NET also provides integrated support for debugging
and deploying ASP.NET Web applications. |
|
Rich
Class Framework.
Application features that used to be hard to implement, or required
a 3rd-party component, can now be added in just a few lines of
code using the .NET Framework. The .NET Framework offers over 4500
classes that encapsulate rich functionality like XML, data access,
file upload, regular expressions, image generation, performance
monitoring and logging, transactions, message queuing, SMTP mail,
and much more! |
Improved
Performance and Scalability
ASP.NET lets you
use serve more users with the same hardware. |
|
Compiled
execution.
ASP.NET is much faster than classic ASP, while preserving the "just
hit save" update model of ASP. However, no explicit compile step
is required! ASP.NET will automatically detect any changes, dynamically
compile the files if needed, and store the compiled results to
reuse for subsequent requests. Dynamic compilation ensures that
your application is always up to date, and compiled execution makes
it fast. Most applications migrated from classic ASP see a 3x to
5x increase in pages served. |
|
Rich
output caching.
ASP.NET output caching can dramatically improve the performance
and scalability of your application. When output caching is enabled
on a page, ASP.NET executes the page just once, and saves the result
in memory in addition to sending it to the user. When another user
requests the same page, ASP.NET serves the cached result from memory
without re-executing the page. Output caching is configurable,
and can be used to cache individual regions or an entire page.
Output caching can dramatically improve the performance of data-driven
pages by eliminating the need to query the database on every request. |
|
Web-Farm
Session State.
ASP.NET session state lets you share session data user-specific
state values across all machines in your Web farm. Now a user can
hit different servers in the web farm over multiple requests and
still have full access to her session. And since business components
created with the .NET Framework are free-threaded, you no longer
need to worry about thread affinity. |
|
Microsoft
.NET Outperforms J2EE.
In a head-to-head comparison of performance and scalability between
Sun's Java Pet Store J2EE blueprint application and the ASP.NET
implementation, Microsoft .NET significantly outperformed J2EE.
The bottom line: the ASP.NET implementation required only 1/4th
as many lines of code, was 28x faster (that's 2700%), and supported
7.6x as many concurrent users as J2EE, with only 1/6th as much
processor utilization. Click here to review the results, download
the code, and run the .NET Pet Shop yourself. |
Enhanced
Reliability
ASP.NET ensures
that your application is always available to
your users. |
|
Memory
Leak, DeadLock and Crash Protection.
ASP.NET automatically detects and recovers from errors like deadlocks
and memory leaks to ensure your application is always available
to your users.
For example, say that your application has a small memory leak,
and that after a week the leak has tied up a significant percentage
of your server's virtual memory. ASP.NET will detect this condition,
automatically start up another copy of the ASP.NET worker process,
and direct all new requests to the new process. Once the old process
has finished processing its pending requests, it is gracefully
disposed and the leaked memory is released. Automatically, without
administrator intervention or any interruption of service, ASP.NET
has recovered from the error. |
Easy
Deployment
ASP.NET takes
the pain out of deploying server applications. |
|
"No
touch" application deployment.
ASP.NET dramatically simplifies installation of your application.
With ASP.NET, you can deploy an entire application as easily as
an HTML page: just copy it to the server. No need to run regsvr32
to register any components, and configuration settings are stored
in an XML file within the application. |
|
Dynamic
update of running application.
ASP.NET now lets you update compiled components without restarting
the web server. In the past with classic COM components, the developer
would have to restart the web server each time he deployed an update.
With ASP.NET, you simply copy the component over the existing DLL
-- ASP.NET will automatically detect the change and start using
the new code. |
|
Easy
Migration Path.
You don't have to migrate your existing applications to start using
ASP.NET. ASP.NET runs on IIS side-by-side with classic ASP on Windows
2000 and Windows XP platforms. Your existing ASP applications continue
to be processed by ASP.DLL, while new ASP.NET pages are processed
by the new ASP.NET engine. You can migrate application by application,
or single pages. And ASP.NET even lets you continue to use your
existing classic COM business components. |
New
Application Models
ASP.NET extend
your application's reach to new customers and
partners. |
|
XML
Web Services.
XML Web services allow applications to communicate and share data
over the Internet, regardless of operating system or programming
language. ASP.NET makes exposing and calling XML Web Services simple.
Any class can be converted into an XML Web Service with just a
few lines of code, and can be called by any SOAP client. Likewise,
ASP.NET makes it incredibly easy to call XML Web Services from
your application. No knowledge of networking, XML, or SOAP is required. |
|
Mobile
Web Device Support.
ASP.NET Mobile Controls let you easily target cell phones, PDAs
-- over 80 mobile Web devices -- using ASP.NET. You write your
application just once, and the mobile controls automatically generate
WAP/WML, HTML, or iMode as required by the requesting device. |
