I Can’t Create Bitmapimage "interface that was marshalled for a Different thread"

Question

Error:

System.Exception: 'The application called an interface that was marshalled for a Different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD))'

I’m trying to get a BitmapImage from a StorageItemThumbnail, but I can’t even create it, whenever I try to create it BitmapImage bitmapImage = new BitmapImage(); get the above error independently if I use Dispatcher.Invoke or not. It is the only line that gives the problem.

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        GetThumbnailFile();
    }

    private async void GetThumbnailFile()
    {
        BitmapImage image  = await ThumbnailPhoto(@"C:\...\");

    }

    private async Task<BitmapImage> ThumbnailPhoto(string FilePath)
    {
        StorageFile sf = await StorageFile.GetFileFromPathAsync(FilePath);
        StorageItemThumbnail fileThumbnail = await sf.GetThumbnailAsync(ThumbnailMode.SingleItem, 250);
        BitmapImage bitmapImage = new BitmapImage();
        bitmapImage.SetSource(fileThumbnail);

        return bitmapImage;
    }
}

Windows 10 API to use Storagefile: Calling Windows 10 Apis From a Desktop Application

Do not work: resolution1, resolution2, Dispatcher.Invoke.

Bitmapimage used: using Windows.UI.Xaml.Media.Imaging;.
