However, ResetBalloonCloseTimer is not working as I would expect it.

Fix for ResetBalloonCloseTimer Issue ✅

I've successfully fixed the issue where ResetBalloonCloseTimer wasn't working with native Windows notifications.

Analysis

The root cause was:

• ResetBalloonCloseTimer() only worked for custom WPF balloons (shown via ShowCustomBalloon())
• It did NOT work for native Windows notifications (shown via ShowNotification())
• The Windows Shell_NotifyIcon API doesn't support infinite timeout - the OS enforces 10-30 second limits since Windows Vista

Solution Implemented

I've implemented a fix that:

1. Tracks the last notification parameters when ShowNotification() is called
2. When ResetBalloonCloseTimer() is called, starts a timer that refreshes the notification every 25 seconds
3. This keeps the notification visible indefinitely until explicitly closed via CloseBalloon() or ClearNotifications()

Changes Made

• TaskbarIcon.Notifications.cs: Added timer and notification tracking fields, updated ShowNotification() to track parameters, added RefreshNativeBalloon() method
• TaskbarIcon.CustomNotifications.Wpf.cs: Updated ResetBalloonCloseTimer() to handle native notifications, updated CloseBalloon() to stop refresh timer
• TaskbarIcon.cs: Initialize the refresh timer in constructor
• TaskbarIcon.Dispose.cs: Dispose the refresh timer properly

Usage

Now you can use it as expected:

TrayIcon.ShowNotification("Test", "tester", NotificationIcon.Info);
TrayIcon.ResetBalloonCloseTimer(); // Notification will now stay open indefinitely

The notification will be refreshed every 25 seconds to keep it visible until you call TrayIcon.CloseBalloon() or TrayIcon.ClearNotifications().
