.net - Can The Select Extension Method Project To A List Of Instantiated Objects

I have two lists declared as follows:

Dim lstDBItems As New List(Of DBItem)
Dim lstAppItems As New List(Of AppItem)

I am trying to do something like this:

I've a function which returns List(Of AppItem):

Function GetAppItems() As List(Of AppItem)
'...
End Function

In the above function I populate lstDBItems and then write the return statement like follows:

Return lstDBItems.Select(Function(x)
dim oItem As New AppItem()
oItem.Property1 = x.DbProperty1

[Code]....

The weird thing is the code compiles, but on rumtime I get a type case error.
