In the ADO.Net Entity Framework Tools CTP2 which is the currently available version, you will most likely run into unexpected behavior when attempting to update your model from database.

If you have created an entity model from your database model, and you decide to add tables and properties to existing tables, then you would expect that an update would add these tables and properties to your entity model existing mapped entities.

However this is not currently the case. The designer will simply add new entities for all tables that doesn't correspond with you entity model.

This makes iterative modeling of entities and database model impossible and is not acceptable for a real life situation.

So i am glad that the ADO.NET team today announced that the next version will fix this issue and add a number of other productivity enhancing improvements to the designer.

Now when can we have it?
