IApplicationResolver interface change in Windows Developer Preview

Question

Hello, IApplicationResolver interface in Windows 8 introduces a couple of new methods as compared to IApplicationResolver in Windows 7. Unfortunately, these methods are inserted in the middle of VMT. Is it possible to make the new interface to be a child of the interface in Windows 7, so the newly added methods would come at the end? I'd be grateful for any response.

Answer 1

I don't see this interface on MSDN which suggests that it's a private interface.  These are internal implementation details of the OS and are always subject to change.  They should not be used by applications.

What functionality of this interface are you looking for?  Perhaps I can help direct you to a supported publicly accessible mechanism for achieving your goal.

Thanks
Brandon

Answer 2

You are right, this is an internal interface in Shell32, which is used by Explorer to retrieve AppIDs for windows, and to get the applications' parameters from their AppIDs. As far as I know there's no publicly available API to get this kind of info.

It's not big deal for us to use two different versions of the interface in different version of Windows. It simply would be easier, if the updated interface was a descendant of the old one.

Answer 3

This thread was created in the Windows Developer Preview: General OS forum; the Microsoft Moderation team has moved the thread to the
Tools for Metro apps forum.
They would be best able to address your issue.

Hi Alexander,

Thank you for your feedback.  IApplicationResolver is not a published interface and wasn't designed to be used by applications.  As you have discovered, its behavior can be modified to meet internal system needs.  That said, since you need a capability that isn't exposed through a published interface, this would be a good opportunity to submit feedback about what you would like to see in a public interface.

Could you please submit feedback using the Windows Feedback Tool from the Connect Site associated with your Windows Developer Preview program?  In your submission, please state how/why you need this functionality and then what you think the desired behavior should be.  We can't promise that we'll be able to publish an interface, but we want to hear your ideas.
