In my Visual studio 2012 for windows phone , I created one project and I developed some pages. It is working fine and i'm able to debug by selecting the desired emulator option. Suddenly the device options tab is not visible. It is looking like below.
For testing purpose I've opened another project, then for this project i'm getting the emulator option. It is looking like this.
I didn't understand why it is happening with the first project. could you please tell me how to enable emulator options for the first project.
Thanks.
