Entity Framework error: Cannot insert explicit value for identity column in table

Question

I\'m getting this error on EF.

Cannot insert explicit value for identity column in table \'GroupMembers_New\' when IDENTITY_INSERT is set to OFF.

Answer 1

Try this:

using System.ComponentModel.DataAnnotations.Schema;
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public decimal Identity_Col { get; set; }

The Entity Framework class file adds these lines of code to the Identity column.
