The Entity Framework 4 CTP5 was just released. There are lots of new features that affect the core use of Entity Framework as well as Code First.
I’ll run through some of these features one blog post at a time. The first is the new T4 Template that gets installed, the ADO.NET DbContext Generator.
This creates a more lightweight context that inherits from DbContext. DbContext was introduced in CTP4 and exposes a simpler way of working with most commonly used features of ObjectContext.
The POCO classes that are generated are much simpler also. Here’s one of the classes. Notice that, unlike the POCO templates we’ve had for a while, these don’t bother with adding in extra logic for two way navigation (the FixupCollection) for the navigation properties.
Since we don’t need the FixupCollection, the additional file that the POCO template created to define the FixupCollection is still there but it is now empty.
