The software giant is hosting two developer conferences--Microsoft TechEd Europe in Barcelona and VSConnections in Las Vegas--where it plans to announce the release of the tools.
One announcement will be for .Net Framework 3.0, the software "plumbing" needed to run and build Windows Vista applications. The software, available as a plug-in to Microsoft's Visual Studio 2005, lets developers write applications that use Vista's new user interface, security features and communications system.
Microsoft is expected to makeavailable to business customers at the end of this month and to consumers in January of next year.
The second launch is for a plug-in to, for building applications that use Excel, Word and other programs in Office 2007. The update is expected to be in broad release early next year.
This add-on will enable developers to write applications that take advantage of the new "ribbon" user interface and other features with Office 2007, said Brian Goldfarb, a group product manager at Microsoft.
Microsoft is also scheduled to release the second beta to its Web development tool kit, called ASP.Net AJAX and code-named Atlas.
This test version is expected to be generally available around the end of this year, when it will be offered as a free download under one of Microsoft's Shared Source licenses, Goldfarb said.
Theis designed to speed up development of Web applications that run in a browser or on a server, he said. Goldfarb added that the software complies with standards and will work with other server-based scripting systems, such as PHP.
One customer, Burton Snowboards, said that using the AJAX Web development technique with Microsoft's Atlas tool has allowed a team of programmers to add more interactivity to its public-facing Web site.
Rather than hire or train more engineers in Adobe's Flash Web development technology, Burton Snowboards decided to train its Visual Studio programmers on the Atlas tool, said Ben Noonan, Internet project and development manager for Burton, in a press briefing arranged by Microsoft.
"Now that our pages are enabled with Atlas, we've seen nearly double the traffic," Noonan said. "The learning curve on the Atlas tool kit was minimal."
