How do I seed Identity roles in ASP.NET Core 2.2 using Script-Migration?

Question

I'm using migrations to create and seed my database. Since my database is running on a separate server from my web application, I'm using Script-Migration to generate a script that I can run on the database server.

According to the official EF Core Docs, we can use HasData to configure seed data for our entities. Is there a way to do this with Identity roles or users?

Answer 1

For seeding data by HasData, it is usually used for your own defined model.

For seeding data for IdentityUser or IdentityRole, it is recommended to use UserManager<IdentityUser> and RoleManager<IdentityRole>. This is due to that there are many properties may not set correctly by HasData like PasswordHash and ConcurrencyStamp.
