Declaring Navigation Property in Entity Framework

Question

Hi,
I developed a sample application in EF which has 3 tables 
PersonDetails, BankDetails and FixedDepositDetails. Please find the table structure below
create table PersonDetails
(PersonId int Primary Key,
PersonName varchar(30))
create table BankDetails
(BankId int Primary Key,
BankName varchar(100),
BankBranch varchar(100),
BankLocation varchar(100))
create table FixedDepositDetails
Id int Primary Key,
FixedDepositNo varchar(30) not null,
Bank_Id int, -- references Bank Details
Person_Id int, -- references Person Details
DOD datetime,
DOM datetime,
DepositAmount decimal(9,2),
MaturityAmount decimal(9,2),
ROI decimal(3,2),
Period varchar(20),
Parent_Id int,
Constraint fk_BankId Foreign Key(Bank_Id) references BankDetails(BankId),
Constraint fk_PersonId Foreign Key(Person_Id) references PersonDetails(PersonId),
Constraint fk_ParentId Foreign Key(Parent_Id) references FixedDepositDetails(Id)
Now in the Entity framework I have specified as given below
[Serializable]
public class PersonDetails
[Key]
public int PersonId { get; set; }
public String PersonName { get; set; }
[Serializable]
public class BankDetails
[Key]
public int BankId { get; set; }
public String BankName { get; set; }
public String BankBranch { get; set; }
public String BankLocation { get; set; }
[Serializable]
public class FixedDepositDetails
[Key]
public int Id { get; set; }
public String FixedDepositNo { get; set; }
[ForeignKey("Bank_Id")]
public int? Bank_Id { get; set; }
public BankDetails BankDetails { get; set; }
[ForeignKey("Person_Id")]
public int? Person_Id { get; set; }
public PersonDetails PersonDetails { get; set; }
public DateTime DOD { get; set; }
public DateTime DOM { get; set; }
public decimal DepositAmount { get; set; }
public decimal MaturityAmount { get; set; }
public decimal ROI { get; set; }
public String Period { get; set; }
[ForeignKey("Parent_Id")]
public int? Parent_Id { get; set; }
public FixedDepositDetails FixedDepositDetail { get; set; }
} public class BaseDBContext : DbContext
        public BaseDBContext(string ConnectionString)
            : base(ConnectionString)
        public DbSet<PersonDetails> PersonDetails { get; set; }
        public DbSet<BankDetails> BankDetails { get; set; }
        public DbSet<FixedDepositDetails> FixedDepositDetails { get; set; }
        protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
            modelBuilder.Entity<FixedDepositDetails>()
                .HasRequired(x => x.BankDetails)
                .WithMany()
                .HasForeignKey(y => y.Bank_Id);
            modelBuilder.Entity<FixedDepositDetails>()
               .HasRequired(x => x.PersonDetails)
               .WithMany()
               .HasForeignKey(y => y.Person_Id);
But when I run the application I get an error as
The navigation property 'Bank_Id' is not a declared property on type 'FixedDepositDetails'. Verify that it has not been explicitly excluded from the model and that it is a valid navigation property.
If I am not wrong I think I have made some mistakes when creating the model. Can some some please let me know where I am doing the mistake? If some one is able to provide me with a solution Please explain me as what you are doing and why that solution needs
to be done?

I know this is an old thread, but when doing it either way you guys described, I get:
"The foreign key component 'FixedDepositDetail' is not a valid navigation property on type 'PersonDetails'.
Verify that it has not been explicitly excluded from the model and that it is a valid primitive property."
I had my own one-to-many relationship, but for the sake of not involving new items, it mirrors this setup from above:
public class PersonDetails
{ [Key]
public int PersonId { get; set; }
public String PersonName { get; set; } public virtual ICollection<FixedDepositDetails> FixedDepositDetail { get; set; }
} public class FixedDepositDetails
[Key]
public int Id { get; set; } public int? Person_Id { get; set; } [ForeignKey("Person_Id")]
public PersonDetails PersonDetails { get; set; } public FixedDepositDetails FixedDepositDetail { get; set; }
Any ideas on how this setup should work, or is this what you guys have?
