Latest features of the ADO.NET Entity Framework

Question

Name the latest features of the ADO.NET Entity Framework 4.0?

Answer 1

ADO.NET Entity Framework 4.0 has following new features:

i. Model-Defined Functions – It enables us to use functions which are described in conceptual schema definition language (CSDL).

ii. Self-Tracking Entities – It refers to entities which are able to track their own alteration. These alterations can be accepted across process boundaries and saved to a database.

iii. Deferred or Lazy Loading – It specifies that associated entities can be loaded automatically whenever necessary. We can allow lazy loading in the application through setting DeferredLoadingEnabled property to true.

iv. Model-First Development – It allows us to create our own EDM and then produce relational model (database) from the EDM by matching tables and relations.

v. Built-in Functions – It enables us to make use of built-in SQL Server functions directly in the queries.

vi. Persistence Ignorance – It permits us to describe our own Plain Old CLR Objects (POCO) that are independent of any detailed persistence technology.
