如何在Entity Framework中加入一对多关系？

public class Author
{
    public int AuthorId { get; set; }
    public string Name { get; set; }
    public ICollection<Book> Books { get; set; }
}

public class Book
{
    public int BookId { get; set; }
    public string Title { get; set; }
    public int AuthorId { get; set; }
    public Author Author { get; set; }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Book>()
        .HasOne(b => b.Author)
        .WithMany(a => a.Books)
        .HasForeignKey(b => b.AuthorId);
}

dotnet ef migrations add InitialCreate
dotnet ef database update
