OPENJSON does not work in SQL Server?
<p>I want to use JSON functions in SQL Server 2016, but when I try to execute <code>OPENJSON</code> function, I get the following error:</p>

<blockquote>
  <p>Msg 208, Level 16, State 1, Line 1<br>
  Invalid object name 'openjson'.</p>
</blockquote>

<p>Why it does not work? I have SQL Server 2016 RC version.</p>
