  <p>However all that is said there is <em>not</em> working. Anyone knows if string interpolation made it into VS 2015? Is there any documentation about it? Can one you give an example?</p>
  
  <p>For instance, none of these formats work (<strong>edited</strong>):</p>
  
  <pre><code>int i = 42;
  var s = "\{i}";  // correction after jon's answer: this works!
  var s = $"{i}";  // compiler error
  var s = "{{i}}"; // no interpolation
  </code></pre>
  
  <p><strong>edit about VS 2015 CTP 6</strong> (20.4.2015 )</p>
  
  <p>The final version is </p>
  
  <pre><code>var s = $"{i}"
  </code></pre>
  
  <p>also supported by the current Resharper version 
  ReSharper 9.1.20150408.155143</p>
