I've uploaded v1.10 to the hosted builders. The xml file is attached (copy it to the internal libraries folder).
You should call Store.RequestProductsInformation(Array(products identifiers, ...)).
The InformationAvailable event will be raised:
Sub store_InformationAvailable (Success As Boolean, Products As List)
If Success Then
For Each p As ProductInformation In Products
Log(p.ProductIdentifier & ": " & p.LocalizedPrice)
Next
End If
End Sub
