public class StaffsBusinessMetadata
{
    [ScaffoldColumn(false)]
    public object ID { get; set; }
}

Answer 1

You'll need to add the MetadataType attribute to the partial class of the Entity type this metadata is for (in this case I assume the Entity is "StaffsBusiness").

[MetadataType(typeof(StaffsBusinessMetadata))]
public partial class StaffsBusiness
{

}
