title: Visual studio 2017 community not finding reference properly
body: <p>I cloned a project on github and while trying to compile, it gives me missing assembly reference error but the said assembly is within the project and seems to be just fine.</p>
  
  <blockquote>
    <p>Error  CS0012  The type 'ValueType' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.   UndertaleModTool Converters\RectConverter.cs    16</p>
  </blockquote>
  
  <p>ValueType is within the dependency ValueTuple.</p>

  <p>Tried re-installing, updating and setting in the csproj file but i wanted to find a clean solution for this problem; other people seem to be able to compile the project just fine.</p>
  
  <p>Any ideas on how to solve this kind of issue?</p>
