    I am working on an application that has a list of songs, and when they select a song it shows the sheet music for it. The sheet music is in png format and they are included in the app file as Content for build action.

    When they select a song, I navigate to a new page just set the PanAndZoomImage source to that file using this code:

    var contentFolder = await global::Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("Content");
    var songAttachmentsFolder = await contentFolder.GetFolderAsync(
    var file = await songAttachmentsFolder.GetFileAsync(item.URL);<br><br>BitmapImage bi =
    new BitmapImage();
    bi.UriSource =
    new Uri(file.Path);
    image.Source = bi;

    Each image file is only about 300KB.

    The application crashes after loading between 3-6 times that control.
    Changing the control from PanAndZoomImage to just the standard Image control it doesn't cause the crash.

    Thank you for writing.

    It will be great if you send us a sample project which reproduces the issue, so we can find exactly what's causing the leak.

    Please note that you need to open a new support ticket in order to be able to attach files.
