を定義していませんか?それは正しい?EntityType「ApplicantPosition」には鍵が
あなたはそれが申請者に関連するだろうし、また位置にあるためApplicantPositionIDは、主キーとして2列の表になります見ることができるように。
つまたは複数の検証エラーは、モデルの生成中に検出されました:
エラーがこの行にスローされるSystem.Data.Edm.EdmEntityType: : EntityType 'ApplicantImage' has no key defined. Define the key for this EntityType.

return View(db.Positions.ToList());

そして、私のモデルは、次のいずれかです。
namespace HRRazorForms.Models
{
public class Position
{
public int PositionID { get; set; }
[StringLength(20, MinimumLength=3)]
public string name { get; set; }
public int yearsExperienceRequired { get; set; }
public virtual ICollection<ApplicantPosition> applicantPosition { get; set; }
}
public class Applicant
{
public int ApplicantId { get; set; }
[StringLength(20, MinimumLength = 3)]
public string name { get; set; }
public string telephone { get; set; }
public string skypeuser { get; set; }

}

}
public class ApplicationPositionHistory
{

public Status oldStatus { get; set; }
public Status newStatus { get; set; }
[StringLength(500, MinimumLength = 10)]

}

私はそれのためにテーブルを作成したいdidntはので、私は申請者クラスに画像を移動しました。そして、必要に応じて[Key]を明示します。今それは正常に動作します。ありがとう –
