title: Could not load file or assembly Nuget packages
body: <p>I have an ASP.Net project which has several sub projects referenced.</p>
  
  <p>I decided today to update some of my nuget packages to have newer versions, what a mistake it was.</p>
  
  <p>Now when I try to debug my app I get this exception:</p>
  
  <blockquote>
    <p>System.IO.FileNotFoundException: 'Could not load file or assembly
    'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral,
    PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The
    system cannot find the file specified.'</p>
    
    <p>InnerException : FileNotFoundException: Could not load file or assembly
    'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral,
    PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The
    system cannot find the file specified.</p>
  </blockquote>
  
  <p>It seems like it's looking to load 6.0.0.0 which is not referenced by any of my subprojects, maybe one of the other nugetpackages ?</p>
  
  <p>I've followed several questions here to perform different operations including:
  - Deleting packages folder in Windows Explorer
  - Reinstalling the Newtonsoft.Json package
  - Clearing the cache of the package in the settings of VS
  - Restoring the packages
  - Cleaning my solution
  - Restarting VS</p>
  
  <p>I'm using VS 2017 community.</p>
  
  <p>I tried to update several other packages to see if it could be linked and I got many new exceptions so I just decided to stop the mess and rollback everything.</p>
  
  <p>But the problem is still here after the rollback so i'm really unsure about what I should do now.</p>
