AWS SDK in Windows 10 Universal App

I'm attempting to use the AWS SDK in a Windows 10 Universal App I'm developing and when trying to import the 'AWSSDK.Core.dll' and 'AWSSDK.S3.dll' in order to use S3 functionality I receive the following error:

A reference to '..\AWSSDK.Core.dll' could not be added. The project targets
'.NETCore' while the file reference targets '.NETFramework'. This is not a
supported scenario. 

Is there something I'm missing that I need to do in order to make use of the SDK or are they just incompatible at this moment in time?
