     The **IoTHubRegistryManager** object exposes all the methods required to interact with device twins from the service. The code first initializes the **IoTHubRegistryManager** object, then updates the device twin for **DEVICE_ID**, and finally runs two queries. The first selects only the device twins of devices located in the **Redmond43** plant, and the second refines the query to select only the devices that are also connected through a cellular network.
