Question

Am I doing something incorrectly with this?

My app went out last night, but I noticed that my code for the free trial wasn’t firing. This method is being called and it always returning FALSE (Full Mode).

What am I doing wrong? Right now my app is free 🙁

    private static Boolean IsTrial()
    {
        #if DEBUG
            return false;
        #endif

        var license = new Microsoft.Phone.Marketplace.LicenseInformation();
        return license.IsTrial();
    }

Currently I have this app sideloaded on my machine. I am updating my pivot header and setting the status for the various checks I have. Right now in the SIDELOADED version it always returns false.

I downloaded my app from the MarketPlace last night (as a Free Trial). The production version is always returning False and so is the Sideloaded version.

Any ideas?

This is my calling code (just in case anyone is interested):

private void MainPage_Loaded(object sender, RoutedEventArgs e)
{

    pivotPills.Title = "PillBox v1.2 - Checking Mode:";
    App.ViewModel.RefreshTrialMode();
    pivotPills.Title = "PillBox v1.2 - Count:" + App.ViewModel.trialItemCollection.Count.ToString();
    //Checking Trial Mode:
    if (App.ViewModel.trialItemCollection.Count == 0)
    {
        trialMode tm = new trialMode();
        tm.IsTrial = true;
        tm.Save();
        pivotPills.Title = "PillBox v1.2 - Trial Mode:" + App.ViewModel.trialItemCollection.Count.ToString();
    }
    else
    {
        if (App.ViewModel.trialItemCollection[0].IsTrial == true) //If saved isTrial = true (still a trial) then check MarketPlace Task
        {
            if (IsTrial() == false) //Purchased App
            {
                App.ViewModel.trialItemCollection[0].IsTrial = false;
                StorageHelper.Save<ObservableCollection<trialMode>>(App.trialModeData, App.ViewModel.trialItemCollection);
                pivotPills.Title = "PillBox v1.2 - Unlimited";
            }
            else //Still in Trial Mode
            {
                //show marketplace window
                NavigationService.Navigate(new Uri("/MarketPlace.xaml", UriKind.Relative));
            }
        }
    }
}

The IsTrial method always returns false when you are running in the emulator (which I presume is the case for you). Check out the How to: Test and Debug Your Trial Application for Windows Phone article on MSDN for help debugging trial applications.
