Visual Studio and WP8 Emulator Error – A specified communication resource (port) is already in use by another application.

I was getting the above error few times back specially when giving presentation. I was spending lot of time identifying the exact cause of the error but ended by knowing that’s a simple one 🙂

The above error was caused because I was trying to run an application on a Windows Phone Emulator from Visual Studio 2012 and there was already another application (in different instance of visual studio) using the same emulator. I stopped the debug of the other application and all was fine. 🙂

  1. I hate when this happens. I’m normally testing multiple apps at once and it’s hard to notice with lots of icons on the taskbar covering it up 🙂
