Answer 1

Here's the same solution as Andy Sinclairs's in VB that worked for me:

Dim pageId as Int64 = 0
Dim signed_request As String = Request.Form("signed_request")
Dim req = FacebookSignedRequest.Parse(AppSettings("FacebookSecret"), signed_request)
Dim data As IDictionary(Of String, Object) = req.Data
If data.ContainsKey("page") Then
    Dim RawPageData As Facebook.JsonObject = data("page")
    If RawPageData.ContainsKey("id") Then
      pageId = RawPageData("id")
    End If
End If
