title: What does the <Class> notation mean?
body: <p>What is the meaning of <code>&lt;&gt;</code> here:</p>
  
  <pre><code>WebHost.CreateDefaultBuilder(args)
    .UseStartup&lt;Startup&gt;()
    .Build()
  </code></pre>
  
  <p><code>Startup</code> is a class but I have only come across &lt;> in enumerable types like lists etc. Please can someone refer to the C# topic I need to look up as googling C# &lt;> produces garbage.</p>
