title: Suppressing warnings for solution
body: <p>I can't seem to be able to suppress warnings in my solution in Visual Studio 2017 by going into <strong>Project Settings > Build > Suppress warnings</strong>:</p>

  <p>Even when I clean - build, rebuild, etc... the solution, Visual Studio keeps bringing up these warnings for me.</p>
  
  <p>I brought this up with <a href="https://developercommunity.visualstudio.com/content/problem/224196/suppress-warnings-from-project-settings-build-does.html" rel="noreferrer">a visualstudio.com report</a> yesterday and it's "triaged" at the moment. Is there an alternative way to suppress warnings in the solution, without marking every single reference?</p>
  
  <p>Version: 15.6.2</p>
  
  <p><strong>Update:</strong>
  This is wierd.
  Visual Studio 2017 uses a semicolon by default, but comma worked.</p>
