JSON in a console application

[oakleaf]

I have a windows form application (VB) that can serialize and deserialize some JSON for me, however, I cannot seem to serialize and deserialize JSON in a console application (the ultimate goal here). I am starting to get the feeling that I am attempting to do something that is not even possible, even though I have seen a couple examples of this being done in C++.

Dim url As String = ""
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)
myHttpWebRequest.Credentials = New NetworkCredential("user", "pass")
myHttpWebRequest.PreAuthenticate = True
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
Dim receiveStream As Stream = myHttpWebResponse.GetResponseStream()
Dim reader4 As New StreamReader(receiveStream)
Dim response3FromServer As String = reader4.ReadToEnd()
Console.WriteLine("responseFromServer: " & response3FromServer)

The above will retrieve the JSON and display it, no problem.

Dim deserializedOrder2 As New CardItems()
Dim ms2 As New MemoryStream(Encoding.UTF8.GetBytes(response3FromServer))
Dim ser2 As New DataContractJsonSerializer(deserializedOrder2.GetType())
deserializedOrder2 = TryCast(ser2.ReadObject(ms2), CardItems)
CardID = deserializedOrder2.CardID
Console.WriteLine(CardID)

Now obviously I have CardItems all set up with members, CardID being one of them, but I can't seem to get the value. Is there a problem with the above?
