Step 7

Run the Windows 8.1 Store app.

For running your Windows app you need to deploy your apps to one of the three options, local machine, remote machine and simulator. In this article I am using simulator.

select simulator

Now build and run the application by pressing the F5 key directly in your keyboard. Press the Start button and you will see the output as shown below.
