title: How can I use escape characters with string interpolation in C# 6?
body: <p>I've been using string interpolation and love it. However, I have an issue where I am trying to include a backslash in my output, but I am not able to get it to work.</p>
  <p>I want something like this...</p>
  <pre><code>var domain = &quot;mydomain&quot;;
  var userName = &quot;myUserName&quot;;
  var combo = $&quot;{domain}\{userName}&quot;
  </code></pre>
  <p>I want the output of <em>combo</em> to be:</p>
  <pre><code>myDomain\myUserName
  </code></pre>
  <p>I get a syntax error about the \ being an escape character. If I put in \\ then the syntax error is gone, but the output is <em>myDomain\\myUsername</em>.</p>
  <p>How can I include escaped characters in an interpolated string?</p>
