title: can not launch app on device
body: <p>I installed Windows 8.1 RTM and installed VS2012 had a little problem while installing windows phone 8 sdk but i guess it is resolved now but still i have a weird problem. </p>
  
  <p>Even i select "device" as the launch target when clicked the run button VS launches the app on the emulator not the phone. Surprisingly if i right click the project on solution explorer and select debug it this time launched app on the device. </p>
  
  <p>Is there anybody faced with this kind of problem? I dont want to install everthing from scratch :) </p>
