Auto Generated Created Updated DateTime on EntityFramework 6 RRS feed

  • Question

  • Hello,

    I want to have CreatedDate / UpdatedDate autoGenerated on Entity Framework 6.

    As its easy to do on EF 7 (EF core) using OnModelBuilder, i didnt find any relevant articles helping me to achieve the same goal on EF 6.

    My configuration is automated migration in code first. I dont have any models.esmx and cant access to up / down migration (sinces its automated).

  • Hi,

    You can do it by Data annotation using following code

    public DateTime Created { get; set; }
    public DateTime Updated { get; set; }

    and in Migration class

     public partial class AddedComputedColumn : DbMigration
            public override void Up()
                AddColumn("dbo.TableName", "Created", c => c.DateTime(defaultValueSql: "GETDATE()"));
                AddColumn("dbo.TableName", "Updated", c => c.DateTime(defaultValueSql: "GETDATE()"));
            public override void Down()
                DropColumn("dbo.TableName", "Created");
                DropColumn("dbo.TableName", "Updated");

    These articles may be helpful

  • Hi Sandeep,

    As i have automated migration, i have no migrations classes.

    For the moment i use a solution found on the web by overriding SaveChanges... best workaround i found.
