VIA Jacky: You can ADO.NET 3.0 CTP from here.

  • The ADO.NET Entity Framework, which includes:
  • The Entity Data Model (EDM), which allows developers to model data at a higher level of abstraction
  • A powerful client-views/mapping engine to map to and from store schemas
  • Full query support over EDM schemas using Entity SQL and LINQ
  • An object services layer that allows you to choose to present query results as rows and columns or as objects. When using .NET objects, the system will transparently do identity resolution, change tracking and update processing for you.
  • An open provider model that allows other stores to plug into the ADO.NET Entity Framework
  • Language-Integrated Query (LINQ) integration in ADO.NET for this CTP includes:
    • LINQ to Entities: formulate queries using LINQ against your EDM schemas
    • LINQ to DataSet: the DataSet finally gets full query capabilities! You can formulate LINQ queries that go against one or more DataTable objects. The LINQ to DataSet implementation will even optimize certain query patterns for better execution performance.
  • Tools
    • We’re working hard to include a rich set of tools that integrate naturally with the runtime components to provide a great end-to-end experience. Some early tools are included in this CTP, and more will come soon!
