        [Required] 
        [MinLength(4)] 
        public string FirstName { get; set; } 
        public string LastName { get; set; } 
        [Required] 
        public string Email { get; set; } 
        public DateTime DateOfBirth { get; set; } 
      } 
    } 

With EF, we will need ContactsContext-a DbContext class-acting as a bridge between the database and the application to perform database-related operations:

 using Microsoft.EntityFrameworkCore; using PacktContactsCore.Model; namespace PacktContactsCore.Context ...
