title: How to use the ternary operator inside an interpolated string?
body: <p>I'm confused as to why this code won't compile:</p>
  
  <pre><code>var result = $"{fieldName}{isDescending ? " desc" : string.Empty}";
  </code></pre>
  
  <p>If I split it up, it works fine:</p>
  
  <pre><code>var desc = isDescending ? " desc" : string.Empty;
  var result = $"{fieldName}{desc}";
  </code></pre>
