Hi Sthitaprajnya The problem with entity framework is that it can work with primary key.By default it recognises Id as primary key if column name is not Id then we need to specify which column is primary key. You need to add 2 namespaces for the above. using System.ComponentModel.DataAnnotations; using System.ComponentModel.DataAnnotations.Schema; Also i could see that [key] attribute is case sensitiveSo make the above changes it will work. [Table(tbl_Employee)] public class Employee { [Key] public int EmpID { get; set; } public string Name { get; set; } public string Gender { get; set; } public string City { get; set; } } If the above solution is helpful then accept the answer.
