body: <p>I am trying to create an App Service web app in the Azure Portal and to connect the web app to my local on-premises SQL Server database using the new Hybrid Connection feature. </p>
  
  <p>Created a simple ASP.NET application using Visual Studio 2015 and trying to connect to the SQL server Database which is on on-prem. And modified the connection String as follows</p>
  
  <pre><code>&lt;connectionStrings&gt;
      &lt;add name="DefaultConnection" 
           connectionString="Data Source=PRAVEEN,1433; User ID=sa; Password=my_password;" 
           providerName="System.Data.SqlClient" /&gt;
  &lt;/connectionStrings&gt;
  </code></pre>
