Perhaps I'm doing something silly ...
I'm using the Leaderboards in my game. I released it on Android without any problems. For the Windows Store (Universal) build I swapped the dll so that I have App42_Unity3D_SDK_2.9.4.dll in my assets folder -( assets/App42-Unity3D-SDK-WP8/App42_Unity3D_SDK_2.9.4.dll).
But in my PostProcessing build I'm getting dozens of errors that all go something like:
Reference Rewriter: Error: type `System.IO.FileStream` doesn't exist in target framework. It is referenced from App42_Unity3D_SDK_WP8_2.9.4.dll
I'm using Windows 8.1 with Unity 4.5.3f
Have spent hours on this one without success - any help would be greatly appreciated!
