The debut of Version 3 was announced Tuesday on the blog of Scott Guthrie, corporate vice president of Microsoft's .NET Developer Division. This version includes many of the changes detailed in a post in April and several new ones, including improvements to the MVC, bug fixes, additions to HTML helper methods and a new URL routing engine that will also "ship in .NET 3.5 SP1 this summer," Guthrie wrote.
Another improvement he highlighted is a richer URL route mapping offering, including support for new characters.
Guthrie also commented on changes planned for upcoming versions. "In future preview releases, you'll start to see more improvements higher up the programming model stack in areas [such as] views (HTML helpers, validation helpers, etc.); AJAX; subcontrollers and site composition; deeper log-in, authentication, authorization and caching integration; as well as data scaffolding support," he wrote.
The preview is available for public download here. The source code is available here.
