I was looking to get the latest EF 4.2 or 4.3 beta but our development environment cannot reach out to the internet. It sits behind firewall which is locked down without our control. We use webdav to transfer files to and from the real world to our development lab and visa versa. How can we can the latest release or beta of EF?

I'm very pleased to read about when the enum support will be on the shelf.

However, not less important than that is have the RIA team develop a matching infrastructure so that those entities are generated in the client as well and act similarly.

Currently, the supported version is EF ≥ 4.0 && < 4.2, which makes even 4.2 impossible in SL projects.

Thanks

@Cygon4: Migrations support is being added in EF 4.3, no need to wait for EF 5.0. I am not completely sure I understand what exactly you are refering to with the term "initialization". EF incorporated APIs to create, drop and verify the existence of a database in 4.0. With Migrations in EF 4.3 we are moving to a model that provides more granular control at the time individual objects are created in the database, providing the ability to specify indexes and default values for columns. In both models the writer of the ADO.NET provider has to implement specific methods in the provider classes to enable this functionality, but you shouldn't need to write database specific code. If by initialization you are refering to the ability to fill the database with seed data, both Migrations and Database Initializers (avialble since EF 4.1) offer this functionality in a database agnostic way.

Seeing support for Migration in EF5, can we also expect that we will be able to initialize the database via Code First in this version?

I'm currently using NHibernate, where I can easily initialize a purely in-memory sqlite database (a feature sadly missing from SQL CE) from my mappings. So far, EF would force me to write database engine specific SQL to initialize the database by hand, for each database engine supported.

Sorry I did not read the full article. So I can now see that Enum support will be in EF 5

I am really looking forward to Enum support. Any idea when we will have this

@Matt,

You should be able to customize Migrations to do this now. You'll need to subclass CSharpMigrationCodeGenerator and override the WriteClassStart method. You can register your custom generator in your MigrationsConfiguration class by setting the CodeGenerator property.

Cheers,

Andrew.

Another question: Is it possible to get the identity of an inserted record mid transaction? It seems like Id always equals zero even after save changes (before transaction.complete). I need the id for sending a transactional MSMQ message.
