ADO. NET Entity Framework I have been paying attention to this architecture for a while, but I have not seen the official release of the architecture because of my busy schedule, and I have not taken the time to learn more about it, Vs2008 SP1 After the release, ADO. NET Entity Framework And Net3.5sp1 Integrated, I think possible ADO. NET Entity Framework Besides Beta3 It should not be released separately. Later versions should Net Framework . Your personal opinion is not worth further consideration.
ADO. NET Entity Framework what are the highlights? See MS msdn description:
the ADO. NET Entity Framework is designed to enable developers to create data access applications by programming against a conceptual application model instead of programming directly against a relational storage schema. the goal is to decrease the amount of code and maintenance required for data-oriented applications. entity Framework applications provide the following benefits:
·Applications can work in terms of a more application-centric conceptual model, including types with inheritance, complex members, and relationships.
·Applications are freed from hard-coded dependencies on a participant data engine or storage schema.
·Mappings between the conceptual model and the storage-specific schema can change without changing the application code.
·Developers can work with a consistent application object model that can be mapped to various storage schemas, possibly implemented in different database management systems.
·Multiple conceptual models can be mapped to a single storage schema.
·Language-integrated query support provides compile-time syntax validation for queries against a conceptual model.
