title: Visual Studio 2017 - how to change .NET version of existing project?
body: <p>I just installed new VS and opened existing project.</p>
  
  <p>It is showing error:</p>
  
  <pre><code>"The C# project "..." is targeting ".NETFramework,Version 4.7" which is not installed on this machine...
  </code></pre>
  
  <p>But I just installed new VS (November 2018) and pretty sure it comes with newer .NET.</p>
  
  <p>What configuration settings I should change to make this work (open existing project with correct .NET version)? </p>
