Using Compile type Resource iso Embedded Resource, just use Uri’s

this.image.Source = new Uri("/Image.png", UriKind.Relative);

// using System.Windows;
        private static BitmapFrame LoadBitmapFromResource(Uri resourceUri)
        {
            using (StreamResourceInfo info = Application.GetContentStream(resourceUri);)
            {
                var bitmapFrame = BitmapFrame.Create(info.stream, BitmapCreateOptions.IgnoreImageCache, BitmapCacheOption.OnLoad);
                bitmapFrame.Freeze();
                return bitmapFrame;
            }
        }
