How to fix the datetime2 out-of-range conversion error using DbContext and SetInitializer?

Question

I\'m using the DbContext and Code First APIs introduced with Entity Framework 4.1.

The data model uses basic data types such as string

Answer 1

Simple. On your code first, set the type of DateTime to DateTime?. So you can work with nullable DateTime type in database. Entity example:

public class Alarme
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }

        public DateTime? DataDisparado { get; set; }//.This allow you to work with nullable datetime in database.
        public DateTime? DataResolvido { get; set; }//.This allow you to work with nullable datetime in database.
        public long Latencia { get; set; }

        public bool Resolvido { get; set; }

        public int SensorId { get; set; }
        [ForeignKey("SensorId")]
        public virtual Sensor Sensor { get; set; }
    }
