Hachamovitch announced the immediate availability of the Internet Explorer Platform Preview for IE9. It is not a full browser but the IE9 engine hosted inside a shell with limited functionality. There is no back button. In fact, there is no toolbar at all. The menu system contains these options:
- Save as File
- Print Preview
- Developer Tools
- Force IE5 Document Mode
- Force IE7 Document Mode
- Force IE8 Document Mode
- Force IE9 Document Mode
- Reset Document Mode to page default
- Report Issue
- Report an Issue
- Run IE9 Diagnostics
- Using the Windows Internet Explorer Platform Preview
- Privacy Statement
Client-side web debugging tools are also included in the preview. The debugger includes network monitoring, script, CSS and HTML debugging.
One of the first updates to the platform preview will include support for HTML 5 video. Microsofts demo machines were loaded with this version and showed off the performance of their video rendering. On a $400 netbook, IE9 rendered two videos using less CPU and with fewer frame drops than Chrome. Next they showed off a video carousel application. It was a carousel in HTML 5 spinning four videos with colored borders and an IE9 background on the page. On Chrome, the CPUs were working hard. On IE9, the CPUs were around 50% utilized. Also, the IE9 version rendered the videos semi-transparent.
Scott Guthrie was on stage next to talk about Microsofts new and upcoming web platform and developer tools, ASP.NET 4 and Visual Studio 2010. Visual Studio improvements for web developers include:
- Full Multi-Monitor Support
- Better IntelliSense
- Reduced Keystrokes and Better Navigation
- Richer Code Visualization, Profiling and Debugging
Scott Hanselman came out to demonstrate some of the new development features coming in Visual Studio 2010. He dragged a code editor window out of the Visual Studio IDE and maximized onto a second monitor to illustrate the multi-monitor support. IntelliSense now supports two new types of autocompletion. First, it will search for results containing the text entered instead of those just beginning with the search text. In addition, if a developer knows the first letter of each word in the desired type/member name, they can type those letters in CAPS to find it. Box selection is possible by holding down the ALT key.
