I'm looking for the fastest way of inserting into Entity Framework

There is some third party library supporting Bulk Insert available:

• Z.EntityFramework.Extensions (Recommended)
• EFUtilities
• EntityFramework.BulkInsert

See: Entity Framework Bulk Insert library

Be careful, when choosing a bulk insert library. Only Entity Framework Extensions support all kind of associations and inheritance and it's the only one still supported.

This library allows you to perform all bulk operations you need for your scenarios:

• Bulk SaveChanges
• Bulk Insert
• Bulk Delete
• Bulk Update
• Bulk Merge

Example

// Easy to use context.BulkSaveChanges(); // Easy to customize context.BulkSaveChanges(bulk => bulk.BatchSize = 100); // Perform Bulk Operations context.BulkDelete(customers); context.BulkInsert(customers); context.BulkUpdate(customers); // Customize Primary Key context.BulkMerge(customers, operation => { operation.ColumnPrimaryKeyExpression = customer => customer.Code; });
