Can't find how to use HttpContent
<p>I am trying to use the below code, but I am not having any luck finding the DLL when I do References/Add Reference.</p>

<pre><code>HttpContent myContent = HttpContent.Create(SOME_JSON);
</code></pre>

<p>I am trying to add <code>Microsoft.Http</code> but it is not in the list. I also tried adding <code>System.Net</code> but same thing, when I do <code>System.Net.Http</code> there is no <code>HttpContent</code> to be used. I would appreciate if anyone could advise me on how I can use the <code>HttpContent</code> functionality.</p>
