title: Multiple assemblies with equivalent identity. .NETFramework Facades
body: <p>On the same code branch we are successfully building on one machine, but on another we get this:</p>
  
  <blockquote>
    <p>Error     Multiple assemblies with equivalent identity have been imported: '...\src\packages\System.Xml.ReaderWriter.4.3.0\lib\net46\System.Xml.ReaderWriter.dll' and 'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.6.2\Facades\System.Xml.ReaderWriter.dll'. Remove one of the duplicate references. </p>
  </blockquote>
  
  <p>How can we resolve?</p>
