title: ASP.NET CORE 1.0, AppSettings from another assembly
body: <p>I have an application splittet into two projects: a web application and a class library. The <code>Startup</code> is only in the web application:</p>
  
  <pre><code>var builder = new ConfigurationBuilder()
      .AddJsonFile("appsettings.json")
  </code></pre>
  
  <p>I wanna have my appsettings.json in that class library and being loaded from there. Is that possible? How can I do that?</p>
