title: Is .NET Core 2.0 logging broken?
body: <p>I can't seem to get Trace level log information outputted after upgrading to .NET Core 2.0 (+ASP.NET Core 2.0).</p>
  
  <p>In fact, if I do a <code>dotnet new web</code>project and add the code below in Startup for Configure, I do not get any trace or debug log messages, but I get the Information and Error messages twice. Commenting out the <code>.AddConsole()</code>call will output these (Information and Error) only once - suggesting that it gets configured automatically with a console provider by default. Keep in mind, this is a "File -> New" project experience, there is nothing setup in <code>Program.cs</code> for logging or configuration at all for this - except for what I've added. Anyone seen things? Or should I register a GitHub issue for it.</p>
  
  <pre><code>public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
  {
      loggerFactory.AddConsole(Microsoft.Extensions.Logging.LogLevel.Trace);
  
      if (env.IsDevelopment())
      {
          app.UseDeveloperExceptionPage();
      }
  
      app.Run(async (context) =&gt;
      {
          var logger = loggerFactory.CreateLogger("Blah");
          logger.LogTrace("Hello world : Trace");
          logger.LogDebug("Hello world : Debug");
          logger.LogInformation("Hello world : Information");
          logger.LogError("Hello world : Error");
  
          await context.Response.WriteAsync("Hello World!");
      });
  }
  </code></pre>
