Question

In my simple class I’m using data annotations to map properties to columns as such:

[Table("Member")]
public class Member
{
    [Key]
    public Guid MemberId { get; set; }

    // More properties go here
}

I can already write new members to my table but MemberId always defaults to a new Guid (0000-000-00…) instead of a beautiful server generated Guid.

I’ve seen scenarios where people change some setting called StoreGeneratedPattern in an EDMX file. But since I’m using Code First obviously I don’t have this EDMX file…

So how would I go about solving this?

Any help is very much appreciated.

UPDATE!!

Ok, just found the answer myself. You can use an annotation.

[Table("Member")]
public class Member
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid MemberId { get; set; }

    // More properties go here
}

Use an annotation:

[Table("Member")]
public class Member
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid MemberId { get; set; }

    // More properties go here
}
