Use Blend

My version of Visual Studio - 2013 - comes with Blend. One of the utilities on Blend

is the capacity to see the screen one has designed on different devices. 

 

Blend is accessible from a right click on the project file.

The interface also creates a phone file, so that one could work on a phone version with
the Emulator should one wish a phone version of the game.

On to the coding!!
