Error CS0012 when building for Hololens

Overview

I am working on a simple prototype. I have a 3D scan of a part which we have prepared into an FBX and would like to view in augmented reality. Scan is fine and object is added to unity however when I build using the latest release of the toolkit on the latest release of Unity I am met with errors on the Visual Studio side of things.

Unity Scene:

Unity Build Window:

Visual Studio Window:

Error I am receiving:

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS0012	The type 'IAsyncAction' is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null, ContentType=WindowsRuntime'.	Assembly-CSharp	D:\Users\cmdann\Development\Games\TurbineAR\Assets\HoloToolkit\Utilities\Scripts\ApplicationViewManager.cs	62	Active

All error output: https://gist.github.com/CMDann/1c843168953160a6c94e00b831b58fc1

Notes:

• I tried cleaning the solution which resulted in more CS0012 errors
• I am running Visual Studio 2017 Enterprise

Expected Behavior

I would like to deploy the application to the Hololens hardware.

Actual Behavior

Errors (CS0012) in visual studio preventing the application from building.

Steps to reproduce

• Attempt to run on device
