Hi,

I’m sorry, I use the code inside the basic example, I put the ToastViewModel class inside my project and I use this code for call it:

private void Image_MouseDown(object sender, MouseButtonEventArgs e) { ShowMessage(_vm.ShowInformation, "Information"); }

    private void OnUnload(object sender, RoutedEventArgs e)
    {
        _vm.OnUnloaded();
    }

    void ShowMessage(Action<string, MessageOptions> action, string name)
    {
        MessageOptions opts = new MessageOptions
        {
            CloseClickAction = CloseAction,
            Tag = $"[This is Tag Value ({++_count})]",
            FreezeOnMouseEnter = false,//cbFreezeOnMouseEnter.IsChecked.GetValueOrDefault(),
            UnfreezeOnMouseLeave = false,//cbUnfreezeOnMouseLeave.IsChecked.GetValueOrDefault(),
            ShowCloseButton = true //cbShowCloseButton.IsChecked.GetValueOrDefault()
        };
        _lastMessage = $"{_count} {name}";
        action(_lastMessage, opts);
        //bClearLast.IsEnabled = true;
    }

    private void CloseAction(NotificationBase obj)
    {
        var opts = obj.DisplayPart.Notification.Options;
        _vm.ShowInformation($"Notification close clicked, Tag: {opts.Tag}");
    }

Of course the versionof your library is the last one and the framework is 7.2. the code above is in the mainWindow.xaml.cs and when I call the show message procedure the program crash immediatly.

I hope this can help you, tank you very mutch.

I guest you didn't initialize Notifier or other object in proper way, try to check examples
