Code to for AutoMapper complex mapping - vb.net

Question

AutoMapper with VB.NET
I have the following classes below. OrderA With List (Of OrderALineItem) and OrderBList With List (Of OrderB). I want to copy data from OrderA to OrderBList. Which copies ItemName, ItemQty, Price from List (Of OrderALineItem) to List (Of OrderB) and OrderID, CustomerName from OrderA itself. I have found almost all codes in C# and am not able to convert it to vb.net code.
Public Class OrderA
Public Property OrderID As String
Public Property CustomerName As String
Public Property OrderLineItem As List(Of OrderALineItem)
End Class
Public Class OrderALineItem
Public Property ItemName As String
Public Property ItemQty As Integer
Public Property Price As Decimal
End Class
Public Class OrderBList
Public Property OrderBLineItem As List(Of OrderB)
End Class
Public Class OrderB
Public Property OrderID As String
Public Property CustomerName As String
Public Property ItemName As String
Public Property ItemQty As Integer
Public Property Price As Decimal
End Class
My VB.NET code until now is:
Dim mapperConfiguration = New MapperConfiguration(Sub(config)
config.CreateMap(Of OrderALineItem, OrderBList)()
End Sub)
Dim mapper = mapperConfiguration.CreateMapper()
Dim objOrderB = mapper.Map(Of OrderBList)(objOrder.OrderLineItem)
The above code creates and object from copies the data from objOrder.OrderLineItem to OrderBList. That's it.
Can anybody help me out on this in VB.NET.
Note: Am totally new in AutoMapper
Version: AutoMapper 6.2.2.0

Done myself, I hope the code below will be helpful to somebody.
Dim mapperConfiguration = New MapperConfiguration(Sub(config)
config.AddProfile(New CustomProfile_1)
End Sub)
Dim objMapper = mapperConfiguration.CreateMapper()
Dim objOrderB As List(Of Dest_OrderB) = objMapper.Map(Of Src_OrderA, List(Of Dest_OrderB))(objOrderA)
Public Class CustomProfile_1
Inherits Profile
Sub New()
CreateMap(Of Src_OrderALineItem, Dest_OrderB)()
CreateMap(Of Src_OrderA, List(Of Dest_OrderB))() _
.ConstructProjectionUsing(
Function(Src1) Src1.List_Src_OrderALineItem.Select(Function(Src2) New Dest_OrderB _
With {.CustomerName = Src1.CustomerName,
.OrderID = Src1.OrderID,
.ItemName = Src2.ItemName,
.ItemQty = Src2.ItemQty,
.Price = Src2.Price}
).ToList())
End Sub
End Class
