Thread.Sleep() in .NET Core on Mac
<p>I'm working with .NET Core on my Mac machine.</p>

<p>Somewhere in my code I want to use this code:</p>

<pre><code>System.Threading.Thread.Sleep(100);
</code></pre>

<p>But it can not find <code>Thread</code> in <code>System.Threading</code> namespace.</p>

<p>What's wrong? Isn't <code>Thread</code> available for Mac, or I'm missing something? </p>
