You should be able to seed the data given your existing model definition.  If the assembly was built correctly then PostSharp will have rewritten the navigation property and the Add method will work.  It's possible this isn't happening for some reason, or that the ibmmx file is either not present or invalid, so double check that PostSharp is referenced and the ibmmx generates correctly.
 
I've attached a simple small solution based on your model which does seed correctly.  Maybe it will help narrow down the problem.

Shouldn't PostScript have rewritten the navigation property by then though?  I have other entities with DF navigation properties that do work in the seed method. (I'm obviously at a loss to see what I've done differently here...)]]> Thu, 07 Jun 2012 06:49:37 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3486&PID=13785#13785 CF Seed Fail : I think your problem comes to... http://www.ideablade.com/forum/forum_posts.asp?TID=3486&PID=13773#13773 Author: Walid

I think your problem comes to the fact Code first migration is 100% Entity framework. The way we have to define the PostTerminals property for devforce isn't the same for Entity Framework (where you would have { get; set; } and not { get {return null;}})
So for code first migration, the navigation property PostTerminals always return null which explain your error when you try add an item to the list.

Hello,
I've coded a few objects like this:

    public partial class AdmSite : EntityBase    {         /// <summary>Gets or sets the AdmSiteId. </summary>        [Key]        [DataMember]        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]        [Column("AdmSiteId")]        [Bindable(true, BindingDirection.TwoWay)]        [Editable(true)]        public int AdmSiteId        {            get;            set;        }. . . 
        [DataMember]        [Bindable(false)]        [Display(AutoGenerateField = false)]        public IbEm.RelatedEntityList<PosTerminal> PosTerminals { get { return null; } }. . .     }

    public partial class PosTerminal : EntityBase    {        #region Data Properties        [Display(AutoGenerateField = false)]        public int PosTerminalId { get; set; }         [Display(AutoGenerateField = false)]        public int AdmSiteId { get; set; }         [IbVal.StringLengthVerifier(MaxValue = 100,            IsRequired = true,            ErrorMessageResourceName = "RequiredString_ValError")]        public string ComputerName { get; set; }         [Display(AutoGenerateField = true,            ResourceType = typeof(PosResources),            ShortName = "PosTerminal_Description_ShortName",            Description = "PosTerminal_Description_Description")]        [IbVal.StringLengthVerifier(MaxValue = 100,            IsRequired = true,            ErrorMessageResourceName = "RequiredString_ValError")]        public string Description { get; set; }        #endregion         #region Navigation        [DataMember]        [Display(AutoGenerateField = false)]        public AdmSite AdmSite { get; set; }        #endregion
	}
In the EF Code First Migrations Seed method, I'm creating data like this:
            AdmSite co =                new AdmSite                {                    AdmSiteId = 1,                    GMTOffset = -5,                    IsActive = true,                    Name = "Central Office",                    CreatedDTS = DateTime.Now                };             context.AdmSites.AddOrUpdate(co);             AdmSite siteHighSchool = new AdmSite            {                AdmSiteId = 2,                GMTOffset = -5,                IsActive = true,                Name = "High School",                AdmSiteIdParent = 1,                CreatedDTS = DateTime.Now            };            context.AdmSites.AddOrUpdate(siteHighSchool);
            PosTerminal terminal1 = new PosTerminal            {                PosTerminalId = 1,                ComputerName = "esaulsberry7",                Description = "Elton's PC"            };            siteHighSchool.PosTerminals.Add(terminal1);            context.PosTerminals.AddOrUpdate(terminal1);             PosTerminal terminal2 = new PosTerminal            {                PosTerminalId = 2,                ComputerName = "kgandy7",                Description = "Kevin's Machine"            };            siteHighSchool.PosTerminals.Add(terminal2);            context.PosTerminals.AddOrUpdate(terminal2);
This fails with:
Running Seed method.System.Data.EntityException: Unable to set field/property PosTerminals on entity type Yargo.DataModel.AdmSite.

Any insight is appreciated.
BTW,
I've also tried:
            siteHighSchool.PosTerminals.Add(terminal1);            context.AdmSites.AddOrUpdate(siteHighSchool);            context.PosTerminals.AddOrUpdate(terminal1);
...
Same error
