Few days ago from Microsoft released ASP.NET 3.5 Extensions CTP Preview. This release brings additional runtime functionality to ASP.NET and .NET 3.5. You can download it here.
Here is what this release includes:
* ASP.NET MVC: This model view controller (MVC) framework for ASP.NET provides a structured model that enables a clear separation of concerns within web applications, and makes it easier to unit test your code and support a TDD workflow. It also helps provide more control over the URLs you publish in your applications, and more control over the HTML that is emitted from them.
* ASP.NET Dynamic Data Support: The ASP.NET 3.5 Extensions release delivers new features that enable faster creation of data driven web sites. It provides a rich scaffolding framework, and will enable rapid data driven site development using both ASP.NET WebForms and ASP.NET MVC.
* ASP.NET Silverlight Support: With the ASP.NET 3.5 Extensions release we’ll deliver support for easily integrating Silverlight within your ASP.NET applications. Included will be new controls that make it easy to integrate Silverlight video/media and interactive content within your sites.
* ADO.NET Data Services: In parallel with the ASP.NET Extensions release we will also be releasing the ADO.NET Entity Framework. This provides a modeling framework that enables developers to define a conceptual model of a database schema that closely aligns to a real world view of the information. We will also be shipping a new set of data services (codename “Astoria”) that make it easy to expose REST based API endpoints from within your ASP.NET applications.
