WPF can't remove a file

Question

I have the following code:

imgScreenshot.Source = new BitmapImage(new Uri(ShellFolder.DocumentsFolder() + System.IO.Path.DirectorySeparatorChar + screenshot.Filename));
File.Delete(ShellFolder.DocumentsFolder() + System.IO.Path.DirectorySeparatorChar + screenshot.Filename);

I get an error:

{"The process cannot access the file 'C:\Users\rover\Documents\MagicScreenshot\vEhWg3Ra20M.jpg' because it is being used by another process."}

I thought about dispose BitmapImage, but this class does not realize this interface. How to write this code correctly?

Try putting the code to delete the file in the event handler for the [`DownloadCompleted`](http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmapsource.downloadcompleted.aspx) event. — Daniel Hilgarth, May 13 '13 at 11:49

Try:

        BitmapImage bi = new BitmapImage();
        bi.BeginInit();
        bi.UriSource = new Uri(ShellFolder.DocumentsFolder() + System.IO.Path.DirectorySeparatorChar + screenshot.Filename);
        bi.CacheOption = BitmapCacheOption.OnLoad;
        bi.EndInit();
        imgScreenshot.Source = bi;
        File.Delete(ShellFolder.DocumentsFolder() + System.IO.Path.DirectorySeparatorChar + screenshot.Filename);
