Why am I seeing 'Windows.UI.Xaml.Input.ICommand' is inaccessible due to its protection ?

Question

I'm just working on some demo code - building on top of WindowsBlogReaderCS.

When I try to add an ICommand to the code I see:

Error 1 'Windows.UI.Xaml.Input.ICommand' is inaccessible due to its protection level C:\Projects\WinRt\WindowsBlogReaderCS\WindowsBlogReaderCS\SplitPage.xaml.cs 186 58 WindowsBlogReaderCS

But I don't understand this at all.

I've read quite a few tutorials and samples - but these are mainly from the developer release, not from the consumer preview release.

Which ICommand should I be inheriting from? Is there a sample anywhere for the consumer preview release?

Thanks

Answer 1

It's about public/protected/internal/private attributes.

Can you show the code ?

Answer 2

I'm literally just trying to add a class that implements ICommand - like   

    public class MyCommand : Windows.UI.Xaml.Input.ICommand
    {
        public EventRegistrationToken add_CanExecuteChanged(EventHandler value)
        {
            throw new NotImplementedException();
        }

        public void remove_CanExecuteChanged(EventRegistrationToken token)
        {
            throw new NotImplementedException();
        }

        public void Execute(object parameter)
        {
            throw new NotImplementedException();
        }

        public bool CanExecute(object parameter)
        {
            throw new NotImplementedException();
        }
    }

Use System.Windows.Input.ICommand.

Please update the documentation to reflect this, then.  I went looking specifically at Windows.UI.Xaml.Controls.Button's Command parameter and it is a Windows.UI.Xaml.Input.ICommand. How is anyone supposed to know to switch to the WPF ICommand?  This makes your APIs very frustrating to use.  Why re-namespace everything if you aren't really going to re-namespace everything? Make this public.
