ASP.NET Dynamic Data 4.0 Preview 4 Refresh

Refreshed 6/26

• DomainDataSource had errors updating foreign keys
• Cannot edit many to many relationship with table per type inheritance
• Better exception handling

The ASP.NET Dynamic Data Preview 4 Refresh is a new release of Dynamic Data based on some of the early bits we are working on for the next release of the framework. This preview release runs on .NET 3.5 SP1 / VS 2008 SP1. The final version will ship with .NET 4.0 and VS 2010.

This preview shows some of the areas in which we are expanding Dynamic Data:

• A new QueryExtender control, contained in the sample projects to simplify common data filtering operations. It supports a rich ASP.NET declarative query syntax that makes it easy to do things like search data for text or have filters based on ranges.
• A new Dynamic Data filter model that enables the developers to apply templates to pages just like field templates (including user defined filters).
• Support for inheritance in Entity Framework and Linq to SQL.
• Support for many to many relationships in Entity Framework.
• New Entity Templates which allow fine control over how an object is displayed and edited.
• Attributes for controlling the filters appearance and order.
• A DomainDataSource control that uses a data provider model which enables the developers to build their own custom business logic.
• A datasource control for ADO.NET Data Services that works with ASP.NET and an ADO.NET Data Service Provider for Dynamic Data.
• Starter templates for building new applications with the bits for DomainService, Entity Framework and Linq to SQL.
• Simple Dynamic Data for adding field templates, validation, and entity template support to existing ASP.NET data driven pages.
