पूरयतु

1. ICompositeCommands अन्तरफलकं CompositeCommands कार्यान्वयनवर्गं च रचयन्तु

Prism मध्ये प्रदत्तं CompositeCommand ऑब्जेक्ट् ICompositeCommands अन्तरफलके तथा ApplicationCommands कार्यान्वयनवर्गे लपेटयन्तु

 public interface IApplicationCommands
    {
        CompositeCommand SaveCommand { get; }
    }

    public class ApplicationCommands : IApplicationCommands
    {
        private CompositeCommand _saveCommand = new CompositeCommand();
        public CompositeCommand SaveCommand
        {
            get { return _saveCommand; }

3. ViewModel मध्ये compound commands परिभाषयन्तु
ViewModel मध्ये एकं कम्पोजिट् आदेशं परिभाषयन्तु तथा च आदेशं View लेयर मध्ये बाइण्ड् कुर्वन्तु
ViewModel: 1।

  private IApplicationCommands _applicationCommands;
        public IApplicationCommands ApplicationCommands
        {
            get { return _applicationCommands; }
            set { SetProperty(ref _applicationCommands, value); }
        }

        public MainWindowViewModel(IApplicationCommands applicationCommands)
        {
            ApplicationCommands = applicationCommands;

4. अन्येषु बहुषु स्थानेषु Commands इत्यनेन सह compound आदेशं पञ्जीकरणं कुर्वन्तु।

 public TabViewModel(IApplicationCommands applicationCommands)
  {
    _applicationCommands = applicationCommands;

    UpdateCommand = new DelegateCommand(Update).ObservesCanExecute(() => CanUpdate);

    _applicationCommands.SaveCommand.RegisterCommand(UpdateCommand);

एवं प्रकारेण यदा ApplicationCommands.SaveCommand इति यौगिक आदेशः प्रवर्तते तदा सर्वे पञ्जीकृताः आदेशाः प्रवर्तन्ते ।
