MY_CONNECTION_STRING needs to be updated, but neither the lab PDF or the accompanying video reference this, unless I missed it?</p><p>&nbsp;</p><p>On this page you suggest the connection string should be copied from the primary connection string of the IoT Hub. This confuses me somewhat as the steps preceding these in the lab are about configuring a Device Provisioning Service. I thought one of the goals of the DPS was to assign the hub to the device? Doesn&#39;t putting the IoT Hub connection string directly in the app bypass the DPS in this instance?</p><img src="https://community.element14.com/aggbug?PostID=7560&AppID=235&AppType=Weblog&ContentType=0" width="1" height="1">
