Get files via .NET

I know the code and APICODE is working because it does return the user accout correctly, but  for whatever reason I cannot list the directories or files.

Using dbx = New DropboxClient("APICODE")
Dim full = Await dbx.Users.GetCurrentAccountAsync()
Console.WriteLine("{0} - {1}", full.Name.DisplayName, full.Email)
ListBox1.Items.Add(full.Email)
Dim list = Await dbx.Files.ListFolderAsync(String.Empty)

For Each item In list.Entries
 If item.IsFile Then
 Console.WriteLine("F{0,8} {1}", item.AsFile.Size, item.Name)
End If

If item.IsFolder Then
Console.WriteLine("D {0}/", item.Name)

End If

Next
End Using
