LINQ to Entities: The
ADO.NET Entity Framework
A lot of hype and information has come out of Microsoft regarding a technology called the
ADO.NET Entity Framework. The ADO.NET Entity Framework is actually a set of technologies
aimed at helping the developer be more productive and efficient. It was designed from day one to
provide developers with the capability to create data access applications by programming against a
known model over the existing method of accessing the database directly.
The ADO.NET Entity Framework is still in its development stages and won??™t be out until after the
initial release of Visual Studio 2008. Because there might be some changes between now and when it
is officially released, this appendix only introduces you to the technology and give you some insight
as to what to expect when it does come out.
