Error when trying to import .NET Assembly AmazonREK DLL created in VS

Hi, I get an error when importing a .NET assembly I have created using Visual Studio 2017 Community- It has one function that utilises the AWSSDK (Rekognition) saying Outsystems.Audit is a missing reference. If I click on browse Outsystems integration studio hangs. and I don't know where to find Outsystems.Auditing

I'm using Outsystems Personal, and my development  version is the latest 10.0.704


Fixed It! - I installed Outsystems 10.0.502 in a separate directory and used the OutSystems.HubEdition.RunTimePlatform from that directory when building my VS Project. I then had to install Build tools version 12.0 for it to work..
