title: error MSB3073 exited with code 1 - .dll issues
body: <p>I'm trying to integrate Cortana to Unity using the following method ( <em>Simon Jackson</em> : <a href="https://www.codeproject.com/Articles/1094232/Making-your-game-stand-out-with-Cortana-on-Windows" rel="nofollow noreferrer">https://www.codeproject.com/Articles/1094232/Making-your-game-stand-out-with-Cortana-on-Windows</a>).</p>
  
  <p>Unfortunately I am facing some issues while building the sample on Visual Studio, here is the error message :</p>
  
  <pre><code>C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\CortanaUnity\CortanaUnity.csproj(245,5): error MSB3073: The command ""C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\Unity\Tools\AssemblyConverter.exe" -platform=uap -lock="C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\CortanaUnity\project.lock.json" -bits=32 -path="." -path="..\Players\UAP\x86\Debug" "C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\CortanaUnity\Assembly-CSharp.dll" "C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\CortanaUnity\UnityEngine.dll" "C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\CortanaUnity\UnityEngine.UI.dll" "C:\Users\P1057\Documents\CortanaUnity\Export\WindowsUniversal\CortanaUnity\UnityEngine.Networking.dll"" exited with code 1.

  <p>It appears that each .dll file of the project products an error. I have read some methods on the forum to correct this problem but none of these works for me. Does anyone has a solution ?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Here is the whole console error :</p>
