位图图像setsource：类型＆＃39; System.ArgumenException＆＃39;的第一次机会异常。发生在mscorlib.ni.dll中

Question

在Windows Universal应用程序中，我正在尝试将可移植库中的图像加载到位图图像中，然后将其放入Image控件中。我遇到的问题是我似乎陷入了bitmapImage.SetSourceAsync（stream）。我找到another user with the problem，但尚未找到解决方案。 我是否需要在png文件上进行某种转换？

编辑我无法真正称之为解决方案，但如果我将图像移出库并进入实际项目，它就可以正常工作。我现在只想和它一起生活。

这是我的代码：

    private async Task<BitmapImage> LoadImageFromLibrary(string original)
    {
        var asm = Assembly.Load(new AssemblyName(LibraryAsmName)); //@"MyProjectLibrary
        string imageName = original + Extension; // e.g. Hir.png
        var bm = new BitmapImage();

        using (var stream = ResourceLoader.GetEmbeddedResourceStream(asm, imageName)
            .AsRandomAccessStream()) // shows a size equal to the size of the .png file
        {
            //await Task.Run(() => stream.Size); // possible online solution... Nope, didn't work.
            await bm.SetSourceAsync(stream); // gets stuck here. Output window shows "A first chance exception of type 'System.ArgumenException' occurred in mscorlib.ni.dll"
        }
        return bm;
    }
