title: NodeJS - @azure/service-bus : How to pass `userProperties` in message to C# backend
body: <p>Before, I was using <code>azure-sb</code> package to handle service bus message in NodeJS with below sample code:</p>
  <pre><code>let message = {
      body: JSON.stringify(body),
      customProperties: {
          userId: userId
      }
  };
  </code></pre>
  <p>However, after changed to use package <code>@azure/service-bus</code>, I needed to change a little bit to get body in C# code as below:</p>
  <pre><code>let signMessage = {
      body: body,
      customProperties: { // tried to use userProperties but not okay
          userId: userId
      }
  };
  </code></pre>
  <p>However, I still cannot get <code>userProperties</code> successfully in C# or ServiceBus Explorer.</p>
