Which .NET frameworks allow you to create Business Entities first, then Database

Question

Do any .NET frameworks allow you to create Business Entities first then Database. In other words allow you to use DDD / Persistence Ignorance method of backing into the database later. Any tools that allow the Models/Classes you have written to generate the SQL DDL and migration scripts.

Feel free to rework my verbiage, and make it a better question.

Answer 1

NHibernate supports domain-driven design, persistence ignorance, and automated data-model generation.
