Entity Framework Tutorial BulkSaveChanges

Introduction

BulkSaveChanges allows you to improve EF performance by saving multiple entities with bulk operations.

Why BulkSaveChanges?

For HUGE performance gains, Entity Framework makes one database round-trip for each entity to insert/update/delete.

So if you want to save (add, modify or remove) 10,000 entities, 10,000 database round trip will be required which is INSANELY slow. To use BulkSaveChanges, you will need to use a third-party library.
