title: Visual Studio 2017 community edition immediate window error: The expression cannot be evaluated while in run mode
body: <p>I want to execute different simple expressions in immediate windows fx. 1+1 but I get that error:</p>
  
  <blockquote>
    <p>"The expression cannot be evaluated while in run mode. "</p>
  </blockquote>
  
  <ol>
  <li><p>I tried to make my project the current startup project but no success.</p></li>
  <li><p>Tried to add ">" in front of 1+1 but no success.</p></li>
  </ol>
  
  <p>I use VS 2017 Community edition.</p>
  
  <p>I have used that immediate window without problem in vs 2015 so this is very annoying.</p>
