Credentials problem - Githubissues

Hi,

I'm trying to instatiate credentials in vb.net with visual studio 2012.

this is the code which I'm implementing:
Imports DotNetOpenAuth.OAuth2

Imports Google.Apis.Auth.OAuth2
'Imports Google.Apis.YouTubeAnalytics
Imports Google.Apis.Services
Imports Google.Apis.Books.v1
Imports Google.Apis.Books.v1.BooksService.Scope
Imports Google.Apis.Books.v1.Data
Imports Google.Apis.Util.Store

'Imports YoutubeManager.BooksService.Scope

Public Class ChannelReports

    Private Sub StartInitialisation()

        Dim scopes As IList(Of String) = New List(Of String)()
        scopes.Add(Books)

        Dim credential As UserCredential

        Dim cs As New Google.Apis.Auth.OAuth2.ClientSecrets
        cs.ClientId = "my client id from api.console"
        cs.ClientSecret = "my clients secrets from api.console"

        credential = GoogleWebAuthorizationBroker.AuthorizeAsync(cs, scopes, "user", CancellationToken.None, fs).Result

but to the credential I'm experiencing this error:
{"Could not load file or assembly 
'Microsoft.Threading.Tasks.Extensions.Desktop, Version=1.0.16.0, 
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. 
The system cannot find the file 
specified.":"Microsoft.Threading.Tasks.Extensions.Desktop, Version=1.0.16.0, 
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"}

I have try also with the method with Filestream, but the same error is showing.

Many thanks in advance for your help
