port from wp7 xna to win 10 using a veiwbox?

I recently ported a wp7 game I originally ported from a Zune HD game. the game and all the art is really built to be 800x480. has anyone tried to wrap the SwapChainPanel inside a viewbox control so the original content will scale to fit the new device?

Be sure to use a scaling chart to see where best to allow borders to form or use Uniform Scaling perhaps?

Personally I would prefer to see a game place borders on the left and right in landscape view as oppose to top and bottom in landscape view as the former method would allow for better text readability if the game is played in landscape view…

Not sure about fiddling with the SwapChain yet though… UWP right?
