Problems overwriting (re-saving) image when it was set as image source

by

You’re almost there.

  • Using BitmapCacheOption.OnLoad was the best solution to keep your file from being locked.

  • To cause it to reread the file every time you also need to add BitmapCreateOptions.IgnoreImageCache.

Adding one line to your code should do it:

  imgTemp.CreateOption = BitmapCreateOptions.IgnoreImageCache;

thus resulting in this code:

  uriSource = new Uri(Combine(imagesDirectoryTemp, generatedFileName), UriKind.Absolute);
  imgTemp = new BitmapImage();
  imgTemp.BeginInit();
  imgTemp.CacheOption = BitmapCacheOption.OnLoad;
  imgTemp.CreateOptions = BitmapCreateOptions.IgnoreImageCache;
  imgTemp.UriSource = uriSource;
  imgTemp.EndInit();
  imgAsset.Source = imgTemp;
