Description

You need to configure the modelBuilder in your context.

Sample

public class AccountingContext : DbContext, IDisposable
{
    public DbSet<Customer> Customers { get; set; }
    public DbSet<Payment> Payments { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        modelBuilder.Entity<Payment>()
                .HasRequired(s => s.Customer)
                .WithMany()
                .WillCascadeOnDelete(true);

        base.OnModelCreating(modelBuilder);
    }
}
