Trying to use convolute on one of the images in my project but the blur doesn't apply to the image at runtime.
StorageFile file = await StorageFile.GetFileFromPathAsync(Model.CurrentUser.BackgroundImagePath);
IRandomAccessStream fileStream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
WriteableBitmap wb = await new WriteableBitmap(1, 1).FromStream(fileStream);
var wb1 = WriteableBitmapExtensions.Convolute(wb, WriteableBitmapExtensions.KernelGaussianBlur3x3);
MainTile.Source = wb1;
