title: Blazor server hosted: Why I can't see any network request while debugging?
body: <p>I've started to learn Blazor. I create a new "Blazor Server App" project on VS 2019 and after creation, just click debug and my project runs fine. The default template has a "Fetch Data" page that has a logic to retrieve data from server side:</p>
  
  <pre><code>forecasts = await ForecastService.GetForecastAsync(DateTime.Now);
  </code></pre>
  
  <p>I added a button to refresh data from server:</p>
  
  <pre><code>&lt;button class="btn btn-primary" @onclick="OnInitializedAsync"&gt;Refresh&lt;/button&gt;
  </code></pre>
  
  <p>And I have opened my Chrome Inspector and watching any network activity. But when I move on pages or on clicking Refresh button, all the logic works fine, but I don't see any new network activity. Only on first time page opening a WebSocket connection occurs.<br/>
  Blazor documents say that it communicates by SignalR using WebSockets but I don't see anything.<br/>
  Could you please describe this?</p>
