Entity Framework auto incrementing field, that isn't the Id

Question

I know this isn\'t the most ideal solution, but I need to add an auto incrementing field to one of my EF Code First objects. This column id NOT the Id, which is a guid.

Answer 1

For those stumbling onto this question for EF Core, you can now create an auto-incrementing column with your model builder as follows:

builder.Entity().Property(e => e.YourAutoIncrementProperty).UseNpgsqlIdentityAlwaysColumn();
