title: Application Insights Not showing Trace.TraceInformation messages
body: <p>I have a .net core web api project. I am simply trying to get my trace statements like below to appear in app insights:</p>
  
  <pre><code>Trace.TraceInformation("Hello World!");
  </code></pre>
  
  <p>I see the log in my output window when I am debugging, but after I deploy, I am not seeing any of my trace statements in the logs.... Why?</p>
  
  <p>I have the <code>Microsoft.ApplicationInsights.AspNetCore</code>, and <code>Microsoft.ApplicationInsights.TraceListener</code> packages included.</p>
  
  <p>I know App insights is setup, because the requests are appearing, and I am getting one trace message from the performance metrics not getting collected (see trace message below):</p>
