Microsoft

→ Browser guy since 1993
(NCSA Mosaic, SPRY Mosaic)
→ Joined Microsoft in 1995
→ Internet Explorer
↑ 2.0, 3.0, 4.0, 5.0, 5.5, 6.0, 7.0
↑ And a stint in Avalon (WPF)
→ Web standards guy
↑ HTML, CSS, DOM, I18n, XSL
→ Now “Platform Architect” of Internet Explorer
↑ (no, I don’t write the code – they won’t let me)

actual adoption of rich web
→Little
platform
→Hard to build rich, sexy apps/content
↑Outlook Web Access \"biggest\" application
bubble burst
→Dot-com
↑Experiments with \"Web OS” and other
super-rich web applications ultimately
failed
developers focused on verticals
→Web
→We also needed a new Windows API

2002: Security Push, Windows XP SP2

With all this going on,
Microsoft seemed AWOL from the web…

→ Simple dev pattern – fetch & update
↑ Realization/innovation on top of Web 1.0
↑ “Caring about the quality of web UI”
→ Rebirth of the semantic Web
↑ RSS
↑ Microformats & tagging add more meaning to
HTML
→ Other Browsers arise!

User Experience
→Amazing
and Trustworthy Browsing
→Secure
Developer Platform
→Web

Streamlined and Improved User Interface
→
↑ Tabbed Browsing with Quick Tabs
↑ Extensible search in UI via OpenSearch
↑ Great default print experience
↑ Page Zoom
↑ Spoof-resistant International Domain Name (IDN)
support
Integrated RSS platform
→
↑ Feed Discovery and default feed view
↑ Common Platform: Feedlist, storage, parser, sync
engine
↑ API from Win32 and .NET Framework

→ Protection against web fraud
↑ Integrated Anti-phishing service
↑ User experience highlights security (EV, address
bar)
→ Putting the User in Control
↑ Add-on Manager (from XPSP2)
↑ We warn user of insecure settings
↑ Explicit user consent is required on first run of
ActiveX
↑ Integration of Parental Controls (Windows Vista
only)

We focused on web developers.

The overflow bug
→
Parser bugs: * html, _property or /**/ comment bug
→
Memory leaks in JavaScript engine
→
Select control: style-able and not always on top
→
Auto-sizing of absolute pos element with right & left
→
great for 3 column layouts
↑
Relative positioning issues
→
% height/width for absolutely positioned elements
→
hover effect working not just over text
→
<?xml> prolog no longer causes quirks mode
→
HTML element truly independent of the Body
→
1 px dotted borders no longer render as dashed
→
…over 200 CSS bugs fixed in IE7…
→
12

→ Fixed inconsistencies with W3C specs
↑ :hover on all elements not just on <a>
↑ Other elements can overlap <select>
↑ Background-attachment: fixed everywhere
↑ Improved <object> fallback
→ Added standards features (CSS/HTML)
↑ Fixed positioning support
↑ Min/Max-Width/Height support
↑ Selectors: first-child, adjacent, attribute, child
↑ CSS 3 attribute selectors: prefix, suffix, substring
13

heavily-requested features
→Other
↑Alpha channel in PNG images
↑“Native” XMLHTTPRequest
the Programming Experience
→Improved
↑Improved JavaScript GC performance
↑Fixed some major memory leaks
↑Fixed Caching of gzipped files

“I’m really concerned that we’re
breaking stuff in the name of
goodness and that all users and
developers will walk away with is
‘stuff broke.’”

→ Compatibility is critical adoption/deployment factor
→ We must balance compliance with site
compatibility
→ In IE7, “quirks mode” stays the same - most
standards changes are only in “strict mode”
→ Unfortunately,standards mode is increasingly
popular, and developers expect behavior to not
change – except when they want it to
16

Readiness Toolkit
→IE7
↑Web developer toolbar – IE6+
↑ Rich tool set for exploring DHTML & CSS
↑ExpressionFinder – shows CSS hacks
↑Application Compatibility Toolkit
↑ Identifies features blocking app compatibility
↑ Fiddler HTTP monitor
↑ And other tools
→ Info on the blog

It’s technically not possible to have EXACT multiple IE
→
versions side-by-side on a single Windows install
↑ There are hacks. They’re fragile, and aren’t complete.
Two months ago (November 30, 2006), we released a
→
free VPC image that contained Windows XP SP2 and
IE6 (Virtual PC is already free) – info on the blog
↑ We expect to release these images on a regular basis
We recently reached a huge milestone – 100,000
→
successful downloads of that 500MB VPC image

→ Web Developer tool supporting HTML, CSS,
XML, RSS, Web Services, JavaScript,
Debugging, validation…
→ …and it’s Free!

A professional tool to create standards-based web
•
sites.
“Passionate about Standards”
•
Generate modern CSS layouts using powerful design
•
tools
Create CSS-based, XHTML 1.0 Web sites by default.
•
Validate your site with compatibility & accessibility
•
reporting
Built-in support for today’s Web standards makes it easy
•
to optimize sites for accessibility and cross-browser
compatibility

XHTML
Browser specific
schemas
Rendering
Schema Errors
Code Snippets

→ Client-sideJavaScript framework for creating
powerful reusable components (and a library)
→ Offers
the interactive user interface benefits of
AJAX with programming model familiar to
ASP.NET devs
→ ASP.NET AJAX isn’t just for ASP.NET
development. You can take advantage of the
rich client framework to build client-centric Web
apps with any backend

A Better Web Experience More Productive Efficient & Effective
– Stunning vector imaging, text, – Web friendly AJAX + – Small, friction-free client
animation, audio and video XML/XAML install (~1.1 MB)
– Multi-platform support, – Javascript programmability – Sandboxed app model
Windows and Mac OS X (Intel – Tap into MS tools ecosystem – Cost-effective delivery of live
and PPC) for developers and designers and on-demand audio/video
– Multi-browser support (IE, Safari, – alpha quality support from with Emmy® Award winning
Firefox) Expression and Visual Windows Media platform
Studio

→ WPF/E is similar to WPF
↑ XAML subset, common tools/developer experience
→ But it’s also different
↑ “WPF/E” is cross platform, WPF is Windows only
↑ \"WPF/E”: differentiated experiences on the web
↑ Size and Features: \"WPF/E\" is 1.1 MB (WPF isn’t ϑ)
↑ Security: \"WPF/E\" is always sandboxed
Target Scenarios:
→
↑ Media/Interactive Content, Rich Internet Applications
CTP build out now; Release in 1st half of 2007
→

Yes, we strongly believe in HTML/CSS/JS platform
→
→ Lots to do in web developer platform – standards,
standards, standards
→ Continue innovating world-class user experience
→ Adding new paradigms as they evolve
→ And as always, security is job #1
Compatibility is crucial for continuity
→
→ Evolution not revolution
