title: Vonk FHIR Facade - Vonk Server could not load file or assembly System.Runtime
body: <p>As I implement Vonk FHIR Facade using the <a href="http://docs.simplifier.net/vonk/facade/facade.html" rel="nofollow noreferrer">link</a>, I've performed all steps successfully uptil <a href="http://docs.simplifier.net/vonk/facade/debugging.html" rel="nofollow noreferrer">this point</a> and placed the resulting dlls in <em>plugins</em> directory. </p>
  
  <p>Now when I start the Vonk server, it fails with following error:</p>
  
  <blockquote>
    <p>Startup Failed: Could not load file or assembly 'System.Runtime, Version=4.2.1.0, Culture=neutral, PublishToken=xxxxxxxxxx' The system cannot find the file specified.</p>
  </blockquote>
  
  <p>I've build my Vonk Facade project in .NET Core 2.1.</p>
  
  <p>Any solution or workaround would be highly appreciated.</p>
