What is ASP.NET? ASP.NET provides a complete environment for building, deploying and

running .NET Web Applications Ease of Development

Simplified page development model

Target any Web client (PC or mobile device)

Modular, well-factored, extensible architecture

Superior debugging and tracing support

Performance, Scalability, Reliability

Compiled, not interpreted

Rich Caching Support

Web farm scalable session state

Automatically detects and recovers from errors

Ease of Deployment and Configuration No need to bring down web server

Deploy and upgrade running apps with XCOPY,

XML Configuration files

ASP.NET Web Forms

ASP.NET makes pages dramatically easier Requires a lot less code to be written

Enables much cleaner code to be written

Can handle automatic uplevel/downlevel scenarios

ASP.NET enables support for server controls

Controls can handle rendering and interaction

ASP.NET Controls

Html Controls Map 1:1 with HTML tags

Server Controls

Render client-targeted HTML and script

Consistent, strongly-typed object model

Some render as single HTML tags Some render richer HTML + script

Mobile Device support

Server controls targeted at Cell Phones/PDAs

Small devices with limited screen real estate

HTML + WML/WAP mobile markup support Automatically handle device incompatibilities

Extensive template customization support

WYSIWYG support within Visual Studio.NET


10/22

Debugging ASP.NET

Tracing ASP.NET supports page and app tracing

Great way to collect request details

Error Handling .NET provides unified error architecture

ASP.NET also provides declarative application custom errorhandling

Global application event raised if unhandled exception occurs

Use new EventLog class to write custom events to log whenerrors occur

Use new SmtpMail class to send email to administrators


11/22

ASP.NET Modular Design

ASP.NET enables customers to replace/extend/customize the core product

Eliminate black box magic with ASP/IIS

Example Customization: Session State, Output Caching,

Authentication/Authorization

Http Runtime: logical replacement for ISAPI API

Enables low-level http programming

Easy programming model for ISAPI-like tasks

ASP.NET can run on any host environment IIS, IE, Apache, SQL, Exchange, etc.

ASP.NET Caching Support ASP.NET provides built-in caching support

that enables re-use of work

Full Page Caching Vary by params, language, user-agent

Partial Page Caching Enables portions of pages to be cached

Web Service Caching Vary by parameters and methods

Cache Engine: Extensible Cache API Enables arbitrary objects to be cached


14/22

Session State

Session State can now be external from ASP.NETWorker Process

ASPState NT Service

SQL Server 7.0

Big reliability wins

Session state survives crashes/restarts

Enables Web farm deployment

Session State can now be shared across a web farm ofASP.NET Servers

Applications no longer tied to one machine


15/22

ASP.NET Web Services

Easiest way to build XML Web Services Author class with methods No special HTTP or XML knowledge required

Supports Multiple Message Wire Formats SOAP messaging support

Http Get/Post return XML payloads

Extensible model for innovation

Interoperate with other SOAP applications

Platform neutral technology


16/22

Improved Code Deployment

Simple deployment for components Just xcopy/ftp to an applications \bin dir

No registration required (no more regsvr32)

No tools, no configuration changes, no appshutdown, no re-boots

Simple uninstall just delete directory

No registry entries to clean up


17/22

Improved Reliability

ASP.NET has been designed with assumption thatfailures will occur on systems

Designing for failure reduced fragility

ASP.NET detects and recovers from problems

Access Violations, Memory Leaks, Deadlocks

ASP.NET supports pre-emptive cycling of apps

Time and Request Based Settings

Net Result: Admins should never think that an ASP.NETapplication is down or unavailable


18/22

Summary ASP.NET provides a quantum leap in power

Tons of new features/infrastructure

ASP.NET will make building web apps easier

Much less plumbing code required

Enable developers to focus on customers

ASP.NET will enable customers to develop a new breedof web applications

More opportunities to build richer apps

Customer reaction has been fantastic
