Public Property Orders() As Orders
        Get
            Return ordersValue

    Private orderIDValue As String
    Public ReadOnly Property OrderID() As String

Hello @Hobbyist_programmer

See if this is helpful, there are some additional properties that may or may not be in your classes. Note Customeridentifier and OrderId would both be -1 until the primary key is returned from inserting a customer, same with order. If this was Entity Framework both keys would be handled by entity framework 6 or entity framework core.

Public Class Customer  
    Public Property Id() As Integer  
    Public Sub New()  
        Orders = New List(Of Orders)  
  
        Orders.Add(New Orders() With {  
            .OrderId = -1,  
            .CustomerIdentifier = -1,  
            .OrderDate = Now})  
  
    End Sub  
    Public Property CompanyName() As String  
    Public Property ContactId() As Integer  
    Public Property CountryIdentifier() As Integer  
    Public Property Orders() As List(Of Orders)  
End Class  
  
Public Class Orders  
    Public Property OrderId() As Integer  
    Public Property OrderDate() As Date  
    Public Property CustomerIdentifier() As Integer  
    Public Property ShipAddress() As String  
    Public Property ShipCity() As String  
    Public Property ShipPostalCode() As String  
    Public Property ShipCountryIdentifier() As Integer  
End Class  
Public Class Country  
    Public Property CountryIdentifier() As Integer  
    Public Property Name() As String  
End Class
