"Apps built with this Go-Live version of the software will run on Windows XP and Windows Server 2003, bringing Vista capabilities
to apps before Vista actually launches," Schmelzer said.
New features in the Go-Live release of Windows Communication Foundation include a service configuration editor, for tweaking
settings, and a service trace viewer, for viewing messages being sent between multiple services. The Go-Live release of Windows
Workflow Foundation features new policy activities to evaluate complex rule sets and a new file format based on XAML (Extensible
Application Markup Language). Microsoft's usage of XAML as a way to specify business processes is unique, Schmelzer said.
Microsoft is not releasing a Go-Live license for Windows Presentation Foundation because this software does not require the
type of scalability testing necessary for the other two technologies, according to Microsoft. The early version of Windows
Presentation Foundation being offered on Wednesday has support for frame-based animations as well as support for applications
accessed through a browser.
In other developer-related news at Microsoft, the company's Visual Studio for Devices and .Net CF (Compact Framework) teams
are eyeing improvements in mobile application development, according to Microsoft executive S. "Soma" Somasegar's blog . Somasegar is corporate vice president of the company's Developer Division. Mobile improvements are anticipated in the planned
Orcas release of the Visual Studio tools platform.
"The Visual Studio for Devices team will continue to invest not only in rapid application development, but also in addressing
end-to-end life cycle management. The device emulator is another area where will continue to invest and enhance," Somasegar
wrote. "Also, the team is also working on delivering an integrated development experience with SQL Mobile, Windows Mobile,
and Windows CE SDKs," he said.
"The .Net CF team is already planning and doing some incubation work on taking some of our new API Frameworks down to device
size," Somasegar wrote. "Another thing that is high on the list of things to get done is the addition of improved 3-D graphics,
sound, and cooperative gameplay APIs, all geared towards the best gaming experience on devices" he added.
No timeframe for shipping Orcas has been set yet, according to a Microsoft representative.
Microsoft also plans to make its Windows Live and Office Live Internet-based services available as rich development platforms, Somasegar said. "Developers will be able to customize, enhance,
and innovate on top of these services," he said. As part of its Internet services plan, the company anticipates improvements
to Visual Studio in the area of building and consuming services.
