        public SetBackgroundColorOfShapeExample()
        {
            // Create a StackPanel to contain the shape.
            StackPanel myStackPanel = new StackPanel();

            // Create a red Ellipse.
            Ellipse myEllipse = new Ellipse();

            // Create a SolidColorBrush with a red color to fill the 
            // Ellipse with.
            SolidColorBrush mySolidColorBrush = new SolidColorBrush();

            // Describes the brush's color using RGB values. 
            // Each value has a range of 0-255.
            mySolidColorBrush.Color = Color.FromArgb(255, 255, 0, 0);
            myEllipse.Fill = mySolidColorBrush; 

            // Set the width and height of the Ellipse.
            myEllipse.Width = 100;
            myEllipse.Height = 100;

            // Add the Ellipse to the StackPanel.
            myStackPanel.Children.Add(myEllipse);

            this.Content = myStackPanel;
        }

    }
