title: Where is the IConfiguration.Get method in ASP.NET 6 (vnext) after update to beta6?
body: <p>For the moment almost all blog posts covering configuration with the new ASP.NET 5 and MVC 6 using json for config is using something like this:</p>
  
  <pre><code>var token = configuration.Get&lt;string&gt;("AppData:CompanyName");
  </code></pre>
  
  <p>For example this question: <a href="https://stackoverflow.com/questions/31453495/how-to-read-appsettings-values-from-config-json-in-asp-net-vnext">How to read AppSettings values from Config.json in ASP.NET Core</a></p>
  
  <p>But since 6 august this function is removed (if you're using bleeding edge releases) with almost no information on what to use instead.</p>
  
  <p>For me this first occurred when switching to from <code>beta5</code> to <code>beta6</code> of <code>Microsoft.Framework.Configuration.Json</code>.</p>
