title: Why do the values of my tuple collection not show up in watch?
body: <p>Why is it that when I run this console app:                             </p>
  
  <pre><code>static void Main(string[] args)
  {
      var items = new List&lt;(string login, string email)&gt;();
      items.Add(("james", "lsdkjsdkj@skdfjd.dfkd"));
      items.Add(("james2", "lsdkjsdkj@df333.dfkd"));
      items.Add(("james", "lsdkjsdkj@skdfjd.dfkd"));
      items.Add(("james2", "lsdkjsdkj@df333.dfkd"));
  
      foreach (var item in items)
      {
          Console.WriteLine(item.email);
      }
  
      var duplicates = items.Where(e =&gt; e.login == "james");
      Console.WriteLine(duplicates.Count());
  
      foreach (var duplicate in duplicates)
      {
          Console.WriteLine($"Found: {duplicate.login}, {duplicate.email}");
      }
  
      Console.ReadLine();
  }   
  </code></pre>
  
  <p>it correctly shows me the contents of the variable <code>duplicates</code>:</p>
