Answer 1

eine ImageBrush der Eigenschaft BorderBrush zuordnen:

var button = new Button 
{ 
    BorderBrush = new ImageBrush(new BitmapImage(new Uri(...))) 
    ... 
}; 

Answer 2

hab es geschafft!

   ImageBrush test1 = new ImageBrush(); 
       test1.ImageSource = new BitmapImage(new Uri("ms-appx:///Assets/myGraphic.png")); 

       Button button = new Button() 
        { 
         FontWeight = FontWeights.Bold, 
         FontSize = 12, 
         BorderBrush = test1, 
         // Foreground = new SolidColorBrush(Colors.Red), 
         VerticalContentAlignment = VerticalAlignment.Bottom, 
         HorizontalContentAlignment = HorizontalAlignment.Center, 
         Content = "my new Button", 
         Tag = i 
        };
