.net - Can I use Data Annotations to perform a Cascade Delete with Entity Framework 4.1 RC?

Question

When using data annotations with EF4.1 RC is there an annotation to cause cascade deletes?

public class Category
{
    public int Id { get; set; }
    [Required]
    public string Name { get; set; }
    public ICollection<Product> Products { get; set; }
}

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Category Category { get; set; }
}

Using this model the constraint generated is:

ALTER TABLE [Product] ADD CONSTRAINT [Product_Category] 
FOREIGN KEY ([Category_Id]) REFERENCES [Categorys]([Id]) 
ON DELETE NO ACTION ON UPDATE NO ACTION;

If not how is it achieved?

Answer 1

Putting required on the Product table Category relationship field solves this

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }

    [Required]  //<======= Forces Cascade delete
    public Category Category { get; set; }
}
