Visual studio 2008 express crashes when writing method call - vb.net

Question

I'm using to Google Calendar API v3 and following the samples to create the windows form application I need. I have an issue in the getAuthorization method provided in the sample.
Basically whenever I write down aut.RefreshToken(... Visual studio crashes
Here's my getAuthorization method:
Private Shared Function GetAuthorization(ByVal arg As NativeApplicationClient) As IAuthorizationState
Dim scopes() As String = { _
CalendarService.Scopes.Calendar.GetStringValue, _
CalendarService.Scopes.CalendarReadonly.GetStringValue _
}
' Get the auth URL:
Dim state As IAuthorizationState = New AuthorizationState(scopes)
state.Callback = New Uri(NativeApplicationClient.OutOfBandCallbackUrl)
Dim refreshToken As String = GetRefreshToken()
If refreshToken <> "" Then
state.RefreshToken = refreshToken
'If arg.RefreshToken(state) Then
' SaveRefreshToken(refreshToken)
' Return state
'End If
End If
Dim authUri As Uri = arg.RequestUserAuthorization(state)
' Request authorization from the user (by opening a browser window):
Process.Start(authUri.ToString())
Dim authCode As String = ""
While authCode = ""
authCode = InputBox("Paste the code provided by Google here:", "Verification code")
End While
' Retrieve the access token by using the authorization code:
Dim result = arg.ProcessUserAuthorization(authCode, state)
SaveRefreshToken(refreshToken)
Return result
End Function
As it can be seen, the arg.RefreshToken block has been commented. If I try to uncomment it or writing it again, VS crashes.
I have to point out that I've tried this code on VS Pro 2010 and worked without any problems

Answer 1

Compiling the method in a dll on its own in VS 2010 worked as I expected, however if anyone ever encountered anything similar, I would appreciate any help as this solution is far from ideal.
