title: Change an Azure App Setting using the portal without a restart
body: <p>I sometimes to this:</p>
  
  <p>In the Azure portal, I go to "App Services", then I click on my web app, and then I go to "Application Settings".</p>
  
  <p>Here I change one value from the "App Settings" list:</p>
  
  <p><a href="https://i.stack.imgur.com/C532m.png" rel="noreferrer"><img src="https://i.stack.imgur.com/C532m.png" alt="App Settings in Azure Portal"></a></p>
  
  <p>Eg. I change "128" to "129"</p>
  
  <p>Finally I click on "Save".</p>
  
  <p>This causes my web app to restart. I don't want that.</p>
  
  <p>Question: Is there a way to manually change this value without a restart? If not, should I store this value in another way then? maybe using a new section in web.config which I can upload each time?</p>
  
  <p>If I use a new section, eg:</p>
  
  <pre><code>&lt;moreAppSettings configSource="moreSettings.config"&gt;
  &lt;/moreAppSettings&gt;
  </code></pre>
  
  <p>And this moreSettings.config is like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;moreSettings&gt;
     &lt;add key="ClientAppBuild" value="129" /&gt;
  &lt;/moreSettings&gt;
  </code></pre>
  
  <p>Can I upload and override that single .config file without a restart?</p>
