title: Duplicate info messages in console of Web API after upgrading to ASP.NET Core 2.0
body: <p>I upgraded a Web API project from ASP.NET Core 1.x to ASP.NET Core 2.0 with very minimal code changes.</p>
  
  <p>When running the WebAPI the command prompt opens up like normal.</p>
  
  <p>However, every single info message is duplicated.</p>
  
  <p>Is this an ASP.NET Core bug or is this an issue on my end after upgrading?</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>I was doing the following in the Startup.cs Configure method:</p>
  
  <pre><code>    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
      loggerFactory.AddDebug();
  </code></pre>
  
  <p>When I remove it there are no duplicates. Is this not needed anymore?</p>
