Anupam Mishra 1410 02-Feb-2016
Hi Everyone,
I have created a class in a model such as follows:
 public class Locations
    {  [Key]
        public int LocationID { get; set; }
        public string Location { get; set; }
    }

I want to create another class schedule in a model  and call the above class primary key fields 'ID' in my schedule class

.Please can anyone give me a solution.

Thank you.

Hi Anupam,
In  your above problem you use a System.ComponentModel.DataAnnotations and 
System.ComponentModel.DataAnnotations.Schema namespace for creating a Schedule class in a model for using  a ID of Location class . Code is as a below:
 public class Schedule
    {
        [Key]
        [Column(Order = 0)]
        public int LocationID { get; set; }
         ..................
    }
