Problems with Application identifier, XNA 4.0 for Windows Phone 8, Visual Studio 2012

Question

I have been developing a game using xna 4.0 that I started developing using a Windows Phone 7.1 phone. When I used the Windows Phone 7.1 phone that I first started developing the game with, there was no problems at all to debug using the phone. At this time I was using visual Studio 2010.

However I recently bought a Windows Phone 8 and now want to continue to develop the game, and I would like to debug the game on the Windows Phone 8. I have therefore downloaded Visual Studio 2012 and Windows Phone SDK 8.0, and have now been trying to deploy the game on the Windows Phone 8 device.

However when I try to do so I get an error message that I haven't found any solution for yet. The error message is:

Application identifier 30F105C9-681E-420b-A277-7C086EAD8A4E is not a valid application identifier.

However when I search my entire project for this identifier, no matches are found.

I found this thread when searching for a solution.

I changed the row for assembly: Guid to the suggested [assembly: Guid("$guid1$")] , but this made no difference.

If you know any solution or tips that can help me find a solution it would be highly appreciated.

Answer 1

Have your try to upgrade? And before you do that make sure that the Windows Phone 7.1 version project has a reference to System.Core.dll and mscorlib.dll before the upgrade.

EDIT

To upgrade/convert try this: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207030(v=vs.105).aspx
