Crash when calling Notify

[Oliver]

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    base.OnNavigatedTo(e);

    try
    {
        rateReminder = new RadRateApplicationReminder();
        rateReminder.RecurrencePerUsageCount = 1;
        rateReminder.SkipFurtherRemindersOnYesPressed = true;
        rateReminder.ReminderClosed += OnRateReminderReminderClosed;
        rateReminder.AllowUsersToSkipFurtherReminders = false;
        rateReminder.Notify();
    }
    catch (Exception)
    {
    }
}

The code above crashes with a COMException. Any suggestions? I'm on the latest official build.

Hello Oliver,

Thanks for writing and for sharing your code.

We are currently not able to reproduce the issue on our side. Could you please isolate the case in a sample project and send it to us for further investigation? If that's not possible, could you please describe the scenario in simple steps so that we can try to reproduce it here?

You will have to open a new support ticket in order to be able to attach files in case you want to.

Thanks for your time.

In fact the call crashes with an InvalidOperationException: ApplicationRuntimeHelper should be initialized before using this component.

Hello Oliver,

Please have a look at the documentation article here, which explains how to initialize the ApplicationUsageHelper.

Let me know if you need additional assistance.

Hi,
I confronted the same problem. Initialization  of ApplicationUsageHelper solved the problem

Private Sub Application_Launching(ByVal sender As Object, ByVal e As LaunchingEventArgs)
    ApplicationUsageHelper.Init("1.1")
End Sub

 Private Sub Application_Activated(ByVal sender As Object, ByVal e As ActivatedEventArgs)
    ApplicationUsageHelper.OnApplicationActivated()
End Sub

P.S: The value of version number didn't affect the workability of the app.

Hello Waleed,

Yes, the ApplicationUsageHelper must be initialized before using RadRateApplicationRemider. It is an application component which is also used by other components, for example RadDiagnostics. When RadDiagnostics reports that an exception has occurred, the report contains the version number that you have used to initialize the ApplicationUsageHelper. This information can help you identify which was the version that crashed so you can easier find the cause for the issue.
