title: How to use azure app service configuration during development
body: <p>Firstly wanna point out that I'm quite new to azure in general (3 days old Junior).</p>
  <p>I have a .NET Framework 4.5.2 app that holds database connection string in Web.config file
  as :</p>
  <pre><code>&lt;connectionStrings&gt;
    &lt;add name=&quot;DBConnectionString&quot; connectionString=&quot;db connection string here&quot; providerName=&quot;System.Data.SqlClient&quot; /&gt;
  &lt;/connectionStrings&gt;
  </code></pre>
  <p>When deploying to Azure as an App Service, I override that configuration by: in the portal.azure.com -&gt; select that App Service -&gt; Configuration -&gt; Connection strings -&gt; New connection string name: DBConnectionString value: db connection string.</p>
  <p>And it works fine, when running locally I have connection string from Web.config, when deployed to Azure it uses connection string from App Service Configuration.</p>
  <p><strong>My question is</strong>: Is it possible to always use App Service Configuration from Azure, even if running app locally on IIS Express during development? If yes, how?</p>
  <p>Thanks for reading this far, and If the question is dumb than I'm really sorry, I just don't know much about Azure yet.</p>
