Cascade delete using Fluent API

Question

I have two entities. Profile and ProfileImages. After fetching a Profile I want to delete ProfileImages through Pro

Answer 1

You can add this to your DB Context:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<Profile>()
    .HasOptional(c => c.ProfileImages)
    .WithOptionalDependent()
    .WillCascadeOnDelete(true);
}

You can configure cascade delete on a relationship by using the WillCascadeOnDelete method. If a foreign key on the dependent entity is not nullable, then Code First sets cascade delete on the relationship. If a foreign key on the dependent entity is nullable, Code First does not set cascade delete on the relationship, and when the principal is deleted the foreign key will be set to null.
