title: Update MVC from 4.0 to 5.2 - Could not install package
body: <p>I'm trying to update my project from MVC 4.0 to 5.2. But As soon I do that I get an error message:</p>
  
  <pre><code>Install-Package : Could not install package 'Microsoft.AspNet.Razor 3.2.3'. You are trying to install this packag
  e into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any assembly referen
  ces or content files that are compatible with that framework. For more information, contact the package author.
