Yes, you can omit the fk property if you have specify the fluent mapping. What EF Code First will do behind the scene is generate a Parent_ParentId field on the db table.

Hi s_tristan;

What do you mean by using "fk properties"? Do you mean using the ForeignKeyAttribute?

In Code First DbContect we can simply avoid using fk properties with that fluent mapping:

modelBuilder.Entity<Parent>().HasMany(parent=>parent.Children).WithRequired(child=>child.Parent);

Is this enough or DevForce needs this fk properties for it's internal infrastructure? Are additional benefits of using fk properties present?
