reading a function issue

Hi,
I am trying to hack some code together from google in a winrt project.  NB I am just starting on store apps.
How do I read the below function...i call it using the below code into a 'task' but am unsure how to read the results of taskk.
         Dim taskk As Task(Of IEnumerable(Of String))         Dim k2 As IMobileServiceTable(Of Item) = App.tester3Client.GetTable(Of Item)()         taskk = ReadingByColumn(k2, "test name2")

    Private Function ReadingByColumn(table As IMobileServiceTable(Of Item), namek As String) As Task(Of IEnumerable(Of String))         Return table.Where(Function(i) i.LastNameK = namek).[Select](Function(i) i.LastNameK).ToEnumerableAsync()     End Function
