WPF menu issue

Question

I Have menu on MainWindow.xaml file

<MenuItem Header="File">
                    <MenuItem Header="Save Job File" Command="ApplicationCommands.Save"/>
                    <MenuItem Header="Open Job File..." Command="ApplicationCommands.Open"/>
</MenuItem>

In App.xaml.cs file I have this:
            CommandManager.RegisterClassCommandBinding(typeof(MainWindow), new CommandBinding(ApplicationCommands.Open, Open, CanOpen));
            CommandManager.RegisterClassCommandBinding(typeof(MainWindow), new CommandBinding(ApplicationCommands.Save, Save, CanSave));

#region Open

        private void Open(object sender, ExecutedRoutedEventArgs args)
        {
            ServiceLocator.Current.GetInstance<IJobFileService>().OpenJobFile();
        }

        private void CanOpen(object sender, CanExecuteRoutedEventArgs args)
        {
            args.CanExecute = true;
        }

        #endregion

        #region Save

        private void Save(object sender, ExecutedRoutedEventArgs args)
        {
            ServiceLocator.Current.GetInstance<IJobFileService>().SaveJobFile();
        }

        private void CanSave(object sender, CanExecuteRoutedEventArgs args)
        {
            // Can only save a job file when a label editor is selected
            args.CanExecute = true;
        }

        #endregion

Hi Dee,

Please try to move the command content in App.cs into your mainwindow.cs.
