title: appsettings.json not getting copied to build package
body: <p>I am using TFS 2018 on-prem to build by ASP.Net Core application. I use the Visual Studio Build task (Version 1.*) with no additional MSBuild arguments. That is I just build my project by pointing to the <code>project.sln</code> file.</p>
  
  <p>The issue is I don't get my <code>appsetting.*.json</code> in my build results so that I can do transformations on it. Both on build agent and my result zip file do not have the JSON file.</p>
  
  <p>In my csproj, I do have the following:</p>
  
  <pre><code>&lt;ItemGroup&gt; &lt;Content Update="appsettings.json"&gt;
     &lt;CopyToOutputDirectory&gt;Always&lt;/CopyToOutputDirectory&gt; &lt;/Content&gt;  
     ... 
  &lt;/ItemGroup&gt;
  </code></pre>
  
  <p>When I build through VS2017, I do get my appsettings.json files copied to the bin folders. If I publish from my VS2017, I get the appsettings.json files in my published folder.</p>
  
  <p>What am I doing wrong? How do I get the TFS to build tasks to copy my JSON files?</p>
