Error implementing parse.com push notifications in WP8

Question

Followed parse.com quickstart guide for an existing WP8 project and It's not working.

Code:

public App()
    {
        // Global handler for uncaught exceptions. 
        UnhandledException += Application_UnhandledException;

        // Standard Silverlight initialization
        InitializeComponent();

        // Phone-specific initialization
        InitializePhoneApplication();

        ParseClient.Initialize("ParseAppId", "ParseDotNetKey");
        this.Startup += async (sender, args) =>
        {
            // This optional line tracks statistics around app opens, including push effectiveness:
            ParseAnalytics.TrackAppOpens(RootFrame);

            // By convention, the empty string is considered a "Broadcast" channel
            // Note that we had to add "async" to the definition to use the await keyword
            await ParsePush.SubscribeAsync("");
        };
    }

Error:

$exception  {System.Reflection.TargetInvocationException: Exception has been thrown by the        target of an invocation. ---> System.NotImplementedException: The method or operation is not implemented.

Don't know what's happening here.
Any help is appreciated.

I had exactly the same error and it looks like Parse uses some classes designed for Windows but not Windows Phone in the latest version of Parse.Phone.dll. The only solution I came up with is using an old version of parse for WP (1.2.16 in my case). Hope you'll find it useful
