title: How to make Nuget.config for my custom repository?
body: <p>I must use <a href="https://www.infragistics.com/" rel="nofollow noreferrer">Infragistics</a> for my project.
  This is the current situation(Package Sources)</p>

  <p>It seems that I haven't explained my intentions. I tried to delete Nuget.org from my NuGet Package Manager( commit and sync in VS 2019). My Nuget.config</p>
  <pre><code>    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
  &lt;configuration&gt;
    &lt;packageSources&gt;
      &lt;!--To inherit the global NuGet package sources remove the &lt;clear/&gt; line below --&gt;
      &lt;add key=&quot;Infragistics&quot; value=&quot;http://localhost:8624/nuget/Infragistics/v3/index.json&quot; /&gt;
    &lt;/packageSources&gt;
  &lt;/configuration&gt;
  </code></pre>
  <p>With this setup,my App Center build fails</p>

  <p>Does anyone have any idea what I should change?</p>
