title: Assign TFS Variable with $ in it
body: <p>I need to assign TFS variable with <code>'MSSQL$Staging'</code>, unfortunately it is only picking up <em>MSSQL</em>. I tried using backtick to escape $ still no luck. When i try to print the value i get only <em>MSSQL</em></p>
  <pre><code>Write-Host &quot;DBInstance = $(DBInstance)&quot;
  </code></pre>
  <p>DBInstance is assigned <code>MSSQL$Staging</code></p>
  <p>Any help would be greatly appreciated.
  Thank you</p>
