Unable to complete operation. The supplied SqlConnection does not specify an initial catalog or AttachDBFileName
<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>

<p>When the application is started its running without any errors as shown in below screenshot1.</p>

<p>But when I try register (enter any record) it throws me with an error as specified in the below Screenshot3....</p>

<p>So, can anyone from the other end help me out please... </p>
