MainWindow.xaml.cs:1

• The System.IO import is removed but line 817 uses System.IO.File.Exists(). This will cause a compilation error. Either restore the using statement or use the fully qualified name System.IO.File.Exists().

MainWindow.xaml.cs:480

• The CheckApplicationUpdateAsync method now always returns false, making this conditional check and early return unreachable. Consider removing this logic since self-update is disabled.

                var updateTriggered = await CheckApplicationUpdateAsync();
                if (updateTriggered)
                {
                    DebugLogger.LogInfo("Update triggered, stopping further processing", "MainWindow");
                    return; // The app will close; updater will restart the new version
                }
