What is EF Core seeding and how do I implement it?

EF Core seeding is the process of populating a database with initial data. You can implement it using the ModelBuilder in your DbContext class.

Can you show me an example of how to seed data in EF Core?

Sure! In your OnModelCreating method, you can use the following code:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Product>().HasData(
        new Product { Id = 1, Name = "Product1", Price = 10.0 },
        new Product { Id = 2, Name = "Product2", Price = 20.0 }
    );
}

Do I need to run any specific commands to apply the seeded data?

Yes, after adding your seed data, you need to run Add-Migration and Update-Database commands to apply the changes to your database.
