EF核心一对多关系HasOne(),WithMany(),vs HasMany(),WithOne()

假设我有以下两种型号：

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }

    public List<Post> Posts { get; set; }
}

public class Post
{
    public int PostId { get; set; }
    public string Title { get; set; }
    public string Content { get; set; }

    public Blog Blog { get; set; }
}

现在，如果我想在DbContext中配置模型关系，那么：

之间有什么区别?

modelBuilder.Entity<Post>()
            .HasOne(p => p.Blog)
            .WithMany(b => b.Posts);

和

modelBuilder.Entity<Blog>()
            .HasMany(b => b.Posts)
            .WithOne(p => p.blog);
