From PDC2009 Day 1: Entity Framework 4
Lots of improvements to EF for 4.0:
- Model-first development.
- Lazy loading through relationships (i.e., no longer have to call Load)
- POCO (i.e., define your own data classes against a model).
- POCO only (i.e., define the model fully in code).
- Code Generation options using the new T4 facility of VS 2010.
- Testability improvements through IObjectSet
- Can override SaveChanges
- Better disconnected workflow (both by writing a little code and a no-code option that uses a different code generator).
- Much better SQL (more compact, more efficient)
- Execute arbitrary SQL
- Easier Stored Procedures
- Functions (a little strange how this was implemented, but now they are available).
- Foreign Keys in the entities (no more manual interpretation of the Reference!)
- Better Binding for forms apps and WPF
Pandelis, what do you think?
