Feature: Add support for Windows 11 new context menu items

[WereWolfix]

Description

I just noticed that if I right click on a folder to compress it, winrar doen't appear as option in the context menu. The only way to compress a folder is to create a winrar archive and that putt the folder.

Steps To Reproduce

1. Install the latest version of WinRar
2. Right click an item in Files and see that WinRar doesn't show up

Expected behavior

• Display WinRar and other options using the new shell apis

Files Version

3.1.7.0

Windows Version

Windows 11 Insider Preview 22543.1000 (rs_prerelease)

Thanks for the report. Could you also add:

• A screenshot of explorer's context menu for the same file
• A screenshot of explorer's "legacy" context menu (the one that appears e.g clicking Shift+F10)
• WinRar version

Please also verify if pressing shift while right clicking makes WinRar appear on Files.

OK that's why. I see Winrar is missing from the legacy context menu and Files does not yet support pulling items from windows 11 menu.
Installing Winrar 5 could be a workaround.

Ah ok. Thank you!

@dahall sorry to bother but in your infinite Win32 knowledge you may know this :)

Is there a way to query the new Windows 11 context menu and enumerate its items?

This is what we're using to get the context menu, but it returns only the "Windows 10" / legacy context menu items.

using var sf = new ShellFolder(@"SOME_FOLDER");
var menu = sf.GetViewObject<Shell32.IContextMenu>(null);
var hMenu = User32.CreatePopupMenu();
menu.QueryContextMenu(hMenu, ...)
...

I was led to believe that Windows 11 menu items implement IExplorerCommand so I was trying to use IExplorerCommandProvider to enumerate them, but I can't figure out how to get that interface.

using var sf = new ShellFolder(@"SOME_FOLDER");
var ecp = sf.GetViewObject<Shell32.IExplorerCommandProvider>(null); // This returns E_NOINTERFACE

I have seen the Windows sample project that successfully gets IExplorerCommandProvider by calling an IShellFolder::CreateViewObject method with it's GUID. Maybe the IShellFolder implementation for that shell item type doesn't support it. You've likely already read this documentation. Have you tried to cast your IContextMenu instance to IExplorerCommand? That's all I can think of.
