- کدهایی که در ماخذ رسمی ذکر شدند، برای حذف پیش فرض‌های EF هست. به صورت پیش فرض OneToManyCascadeDeleteConvention وجود دارد. اگر بخواهید در همه جا آن‌را حذف کنید، modelBuilder.Conventions.Remove را بر روی آن فراخوانی کنید. اگر نیاز است فقط در یک رابطه‌ی خاص این مورد حذف شود از متد WillCascadeOnDelete با پارامتر false استفاده کنید.
- همچنین مطابق این ماخذ: اگر کلید خارجی مدنظر نال پذیر باشد (مانند نوع‌های nullable صریح و یا string و امثال آن)، حذف آبشاری را اعمال نمی‌کند. فقط یک سر رابطه را نال کرده و آن‌را حذف می‌کند.

If a foreign key on the dependent entity is not nullable , then Code First sets cascade delete on the relationship
