Possible to set column ordering in Entity Framework

I'm assuming you are using Entity Framework 6 since column ordering is not yet supported in EF Core.

You can use either data attributes or the fluent API to set column order.

To use a Data Attribute to set column order, reference System.ComponentModel.DataAnnotations and use the ColumnAttribute. You can also set the column name with this attribute if you want it to differ from the property name.

[Column("CreatedAt", Order=0)]
public DateTime CreatedAt { get; set; }
[Column("CreatedBy", Order=1)]
public int CreatedBy { get; set; }

Note the Order parameter is zero-based.

Alternatively, you can use the Fluent API in the OnModelCreating method in your DbContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    //Configure Column
                .Property(p => p.CreatedAt)

This way is a bit more verbose but you can have a more bit control over what's happening.
