title: Combine string interpolation and string.format
body: <p>I'm just wondering if there is a possibility to combine string interpolation, which was introduced in C# 6.0 and string.format? Any smarter ideas like this?</p>
  
  <pre><code>string fancyString = $"My FancyString was created at { DateTime.Now }" + " and I want to add some static with string.format like {0}";
  </code></pre>
