what does navigation property in model creation

Hi Kiran Jagtap,

Navigation properties are essential components of Entity Framework Core that facilitate the representation of relationships between different entities in your data model. They allow you to navigate from one entity to another, effectively linking them through foreign key relationships.

For instance, consider a scenario where you have two entities: Author and Book. An Author can write multiple Books, establishing a one-to-many relationship. In your Book model, you would define a navigation property to the Author entity, as shown below:

public class Author
{
    public int AuthorId { get; set; }
    public string Name { get; set; }
    public ICollection Books { get; set; } // Navigation property
}

public class Book
{
    public int BookId { get; set; }
    public string Title { get; set; }
    public int AuthorId { get; set; } // Foreign key
    public Author Author { get; set; } // Navigation property
}

Navigation property in entity framework represents the relationship between two entities that allows easy navigation of related data. so yes you can use navigation property in your case.
