Hello, @dahall

I'm working on the WinUI3 stuff using the brand new IconExtractor again.

When enumerating some special folders, the IconExtractor throws errors when then trying to get the DisplayName:

Code involved at public void ExtractChildItems( ... ):

        Debug.Assert(targetFolder.IsFolder);
        Debug.Assert(targetFolder.ShellItem.PIDL != null);
        var shItemId = targetFolder.ShellItem.PIDL;
        var shFolder = new ShellFolder(shItemId);
        var shellIconExtractor = new ShellIconExtractor(shFolder);
        shellIconExtractor.IconExtracted += (sender, args) =>
        {
            var shItem = new ShellItem(args.ItemID);
            var ebItem = new ExplorerBrowserItem(shItem);

            DispatcherQueue.TryEnqueue(() =>
            {
                CurrentFolderItems.Add(ebItem);
            });
        };
        shellIconExtractor.IconExtracted += iconExtOnIconExtracted;
        shellIconExtractor.Complete += iconExtOnComplete;
        shellIconExtractor.Start();

...

    public ExplorerBrowserItem(ShellItem? shItem, bool isSeparator = false)
    {
        ShellItem = new ShellItem(shItem.PIDL);
        DisplayName = ShellItem.Name ?? ":error: <DisplayName.get()>";
        IsExpanded = false;
        // todo: If IsSelected, add overlay of opened folder icon to TreeView optionally
        IsSelected = false;
    }

The folders that don't work are virtual ones: Home, This PC, Network.

You can (hopefully) build the branch involved from this:

Any ideas? Didn't debug into your code, cause I'm not privileged enough to understand it 🤣

Keep in mind, that there are no icons involved, no navigation is working ⚒

Any thoughts on this?

Thank you very much,

You don't have to care. I'm bringing in Unit-Tests for this Issue, to track it down...
