这是用户和计算机的一对一关系：

public class User
    {
        public User() 
        { 
        }

        public int idUser; { get; set; }
        [Required]
        public string UserName { get; set; }


        public virtual Computer Computer{ get; set; }

    }


public class Computer
    {
        public Computer() 
        {
        }
        [Key, ForeignKey("User")]
        public int idUser{ get; set; }

        public string ComputerName {get;set;}

        public virtual User User { get; set; }
    }

引用您的代码：

[Table("User")]
public class User
 {
  [Key]
  public int idUser;
  public int idComputer; 
  public virtual Computer Computer;
 } 

[Table("Computer")]
 public class Computer
 {

  [Key, ForeignKey("User")]
  public int idComputer;
  public virtual User User;

 }
