Working with the Blog entity

We have discussed in detail the Blog model in Chapter 1, Kickstart - Introduction to Entity Framework Core, but still, the following highlighted part looks pretty new to us:

• The Blog() constructor initializes the Post property, which ensures that the collection has a concrete HashSet list created and ready to accept any new items
• The Post property has a virtual keyword, which instructs EF to lazy load the navigational property Post:

        public partial class Blog
        {
          public Blog()
          {
            Post = new HashSet<Post>();
          }
          public int Id { get; set; }
          public string Url { get; set; }
          public virtual ICollection<Post> Post { get; set; }
        }

There is nothing much to explore in the Blog class so, let's move on to the Post class.
