Random 'cannot access disposed object' when using custom loaded image

[huoyaoyuan]

Describe the bug

I'm using BitmapSource.SetSourceAsync to load images, because the loading requires authorizing so that cannot be achieved by UriSource.

The image is used in a virtualized GridView.

Loading code snippet:

                if (request is null)
                {
                    image.Source = null;
                    loadingProgress.IsActive = false;
                    copyCommand.NotifyCanExecuteChanged();
                    return;
                }

                var bitmap = new BitmapImage();
                image.Source = bitmap; // the Image control inside the user control
                loadingProgress.IsActive = true; // a ProgressRing
                copyCommand.NotifyCanExecuteChanged();

                try
                {
                    // performing the load
                    var entry = await _imageCache.GetImageAsync(request, refreshMemoryCache).ConfigureAwait(true);

                    var stream = entry.GetWinRTStream();

                    if (image.Source == bitmap) // if the control has been reused for virtualization, discard it
                    {
                        _currentEntry = entry;
                        loadingProgress.IsActive = false;
                        copyCommand.NotifyCanExecuteChanged();

                        await bitmap.SetSourceAsync(stream);
                    }
                }
                catch
                {
                    if (image.Source == bitmap)
                        loadingProgress.IsActive = false;
                }

I cannot find anything useful here.

If the application is launched with debugger, the exception will be ignored. One image control which seems triggers the exception will be empty.

If the application is launched without debugger, it will crash.

Looks like a duplicate of microsoft/CsWinRT#640

Maybe not. The exception call stack is totally native. No managed exception incurred here.

Edit:
Confirmed that the CsWinRT fix doesn't resolve this issue. This is another one.

Further information:

If I change the call to synchronized SetSource AND change the backing stream to WinRT InMemoryRandomAccessStream, the issue seems to disappear.

Projected .NET stream with SetSource will get a deadlock in UI thread.

It seems to be caused by the source stream containing corrupt image. (NOT confirmed - seems wrong)

[huoyaoyuan]

Whether .NET or WinRT stream passed into it can cause different exceptions. This indicates a CsWinRT issue. Moving to them.

No longer reproduces when updating to latest CsWinRT.
