title: NuGet Json.Net Install Erros VS 2010 Shell
body: <p>I am trying to install NuGet do that I can use Json.Net Extensions.</p>
  
  <p>I have installed version 2.8.60318.667 (which was the download from Microsoft for VS2010.</p>
  
  <p>When I try and install Json.Net by the Package Manager Console it fails</p>
  
  <pre><code>    PM&gt; Install-Package Newtonsoft.Json
  Attempting to resolve dependency 'Microsoft.CSharp (≥ 4.3.0)'.
  Install-Package : 'Microsoft.CSharp' already has a dependency defined for 'System.Dynamic.Runtime'.

  when I then try to install Microsoft CSharp extension I get this error
  <a href="https://i.stack.imgur.com/Z1J0r.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Z1J0r.png" alt="Microshoft CSharp Error"></a></p>
  
  <p>When I click the Upgrade NuGet button at the bottom there is no update to 2.12 and the only thing I can find is for VS 2013</p>
  
  <p>Is there a way to get this extension to work for VS2010 Shell?</p>
