Access appsettings.json from .NET 4.5.2 project : <p>I have two projects, a 1.1.0 ASP.NET Core project and a reference to a 4.5.2 project.</p>

<p>I want to get values from the appsettings.json file to my 4.5.2 project. The appsettings.json file is in the core project.</p>

<p>Tried this from my 4.5.2 project with no luck:</p>

<pre><code>var mailServer = ConfigurationManager.AppSettings["MailServer"];
</code></pre>

<p>How can I access the values from my 4.5.2 project?</p>
