Entity Framework Bulk Merge

Introduction

BulkMerge allows you to improve EF performance by merging multiple entities with bulk operations.

Why BulkMerge?

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

So if you want to modify 10,000 entities, 10,000 database round trip will be required which is INSANELY slow. To use BulkMerge, you will need to use a third-party library.
