I’d like to turn your attention to two blog posts on EF Design Blog about exciting new features planned for Entity Framework:

• Foreign Key Support – we’re introducing new type of association, which can be manipulated through references OR foreign key values available on entities themselves. We believe that this will greatly improve scenarios such as data binding, disconnected entities (N-Tier) and many others.
• Self-Tracking-Entities – it’s a simple way to have your entities track their state across tiers (based on custom code generation) and simple mechanism to save those changes to the database.

Your feedback is very important to us, please tell us what you think about those new features!
