How to insert a large number of records quickly using ADO.Net Entity Model?

I am using the ADO.Net Entity Model. Everytime I create a 开发者_C百科record, I am calling _entity.AddToTable(object); _entity.SaveChanges();

What is the fastest way of inserting the data? Is there any "batch" or "SqlBulkCopy" option for entity model?
