Entity Framework Bulk Insert Throws KeyNotFoundException error

Question

I am using EF6 and due to the low speed of AddRange() method I need to use BulkInsert. So I added the NuGet package of BulkInsert for

Answer 1

The "BulkInsert" library is very fast but not very flexible and unsupported.

It doesn't support all type of inheritance (TPC, TPT) and has some issue with column mapping.

The issue you got is for one of these reasons.

This library is the ultimate library for performance and allow to:

• BulkSaveChanges
• BulkInsert
• BulkUpdate
• BulkDelete
• BulkMerge

All inheritance and association are supported.

Example:

using (var db = new Entities(myConnectionString)
{
    db.BulkInsert(contactsToInsert);
}

// BulkSaveChanges is slower than BulkInsert but way faster then SaveChanges
using (var db = new Entities(myConnectionString))
{
    db.Contacts.AddRange(contactsToInsert);
    db.BulkSaveChanges();
}
