Please try this code

// Create a red rectangle that will be the target
// of the animation.
Rectangle myRectangle = new Rectangle();
myRectangle.Width = 200;
myRectangle.Height = 200;
Windows.UI.Color myColor = Windows.UI.ColorHelper.FromArgb(255, 255, 0, 0);
SolidColorBrush myBrush = new SolidColorBrush();
myBrush.Color = myColor;
myRectangle.Fill = myBrush;

// Create the transform
TranslateTransform moveTransform = new TranslateTransform();
moveTransform.X = 0;
moveTransform.Y = 0;
myRectangle.RenderTransform = moveTransform;

// Add the rectangle to the tree.
LayoutRoot.Children.Add(myRectangle);
// Create a duration of 2 seconds.
Duration duration = new Duration(TimeSpan.FromSeconds(1.0));
// Create two DoubleAnimations and set their properties.
DoubleAnimation myDoubleAnimationX = new DoubleAnimation();
Storyboard sb = new Storyboard();
sb.Duration = duration;
sb.Children.Add(myDoubleAnimationX);
Storyboard.SetTarget(myDoubleAnimationX, moveTransform);
Storyboard.SetTargetProperty(myDoubleAnimationX, "X");

myDoubleAnimationX.To = 0;
myDoubleAnimationX.From = 340;

// Make the Storyboard a resource.
LayoutRoot.Resources.Add("unique_id", sb);

// Begin the animation.
sb.Begin();

Thanks,
