Microsoft on Wednesday released a host of developer technologies aimed at creating rich Internet applications (RIA), including a beta of the next version of Internet Explorer (IE) that the company hopes will promote the development of applications that have the same look and feel across different browsers.

Technologies that developers can now get their hands on include betas of Internet Explorer 8, Silverlight 2 and Expression Studio 2. Silverlight 2 is an update to Microsoft's cross-browser software for building and delivering multimedia applications on the Web, and Expression is Microsoft's graphic and Web-design suite. Microsoft released updates of the products at its annual MIX 08 conference, which kicked off in Las Vegas on Wednesday.

IE 8 made its public debut at the show in a demonstration by Dean Hachamovitch, IE general manager at Microsoft. In particular, he seemed keen to show uniformity of application experiences between IE 8 and competing browsers Mozilla Firefox and Apple Safari.

Microsoft developed IE before some Web standards, such as CSS (Cascading Style Sheets) and RSS, were developed, and so older versions of the browser don't support them. When IE took off as the de facto standard, developers would write applications to work with IE rather than to support Web standards. Microsoft also was lax in updating IE to meet the demands of standards because there was little competition in the browser market for years.

With the release and subsequent popularity of open-source browser Mozilla Firefox three years ago, IE's need to stay current with Web standards -- so that Web pages could be developed once to look the same across all browsers -- became more important. When Microsoft developed IE 7, released in October 2006, the company had good intentions and decided to improve support of Web standards with the new release.

However, Web sites that were created for older versions of IE didn't work properly on IE 7, and applications developed for IE 7 didn't work the same way on Firefox and Safari. This is a problem that Microsoft is determined to remedy with IE 8, Hachamovitch said Wednesday.

"We want to get the Web pages to look the same on all the browsers," he said. "IE 8 will interoperate with Web content in the most standards-compliant way it can."
