title: Turn off any IntelliSense, compiler notices and warnings, and suggestions in Visual Studio 2019
body: <p>I need to present a C# application's code as part of a presentation and it must be presented in the IDE itself. Thus, I want to disable any IntelliSense / compiler notices / warnings / code suggestions that might pop up mid-presentation, leaving only color coding.</p>
  <p>For example, I do not wish dotted green and blue lines under fields like so:</p>
  <p><a href="https://i.stack.imgur.com/TLdP2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TLdP2.png" alt="enter image description here" /></a></p>
  <p>How can I turn those off, and how can I turn them back on after presentation?</p>
  <p><em>(Note: I use resharper for C#.)</em></p>
