I have been having this issue for a couple of days. I have the following error when I try to build my Unity project as a Windows Store project using Windows 8.1 SDK.
Could not start compilationException: ‘References\CommonConfiguration\Neutral\Windows.winmd’ not found, do you have Windows Phone 8.1 SDK installed ?
The thing is, I have the Windows Phone 8.1 SDK installed on my computer. The SDK path is C:\Program Files (x86)\Windows Kits\8.1\References\CommonConfiguration\Neutral\Windows.winmd". I don’t understand why the SDK isn’t found.
Is there a way to redefine the path of the Windows Phone 8.1 SDK in Unity ? Or where should I move the SDK ?
The Windows 8.1 SDK was not the Windows Phone SDK but the desktop one (for computer apps). I simply had to download Visual Studio for Windows 10 and select the pluggin for Windows Phone development kit during the installation.
Phnoe SDK is not In Window SDK its have different folder name Windows Phone Kits. This folder is locate in C:/Programefiles(x86)/windowsphonekits.If you have visual studio 2013 you just update VS with latest update.In my case I just update VS with update 5 and i got windows 8.1 SDK. If you just want to install only 8.1 then u should update VS with minimum update 2 then 8.1 SDK install. You can get SDK from this link
