Hi guys I think it's been reported as a bug. We're using HOTWeen in our project. The same code builds right for Windows Phone 8 but fails for Windows Store. The issue is open here too: https://code.google.com/p/hotween/issues/detail?id=79 I can build the game in Unity and build it in Visual Studio without issues. The problem appears when running the game. We've released our game Minimonsters Crush, for iOS, Windows Phone, Android, and MacOSX, but we can not submit it for Windows Store, because this issue. Please can you help us. We've applied every patches since 4.5.2 with the hope to found this issue fixed, but there is no way. Thank you.
