title: Managing References in Visual Studio
body: <p>Although <code>System.IO</code> is not listed in the References that resides in the <code>Solution Explorer</code>, opening <code>Object Browser</code> shows this reference. And when a Nuget package installs and references a newer version and adds it to the References, VS complains during build:</p>
  
  <blockquote>
    <p>Multiple assemblies with equivalent identity have been imported.</p>
  </blockquote>
  
  <p>But I just want the Nuget's System.IO, not .NET Framework's. How can I fix it?</p>
