I managed to fix a similar build stop error which I encountered on 4.5.3f3 building for Windows 8 Store.
My issues was that I had to update code to not use incompatible interfaces with the Windows Store. With the removal from our code of the 3 unsupported Windows Phone and Windows 8 interfaces, the problem was completely eliminated. So I would recommend building with "Use Net Core" and double checking that you are only using compatible interfaces with the Windows Store/Windows Phone frameworks.
