For our purposes, we start with the device set of interfaces for provisioning. We add a member variable that will hold our provisioning client to both our SensorXmpp2 and ActuatorXmpp2 projects:

private ProvisioningClient provisioningClient = null;

When we search the components made available by the server to find a Thing Registry, we make sure to check for provisioning support as well:

if (e2.HasFeature(ProvisioningClient.NamespaceProvisioningDevice)) 
{ 
   Log.Informational("Provisioning server found.", Item2.JID); 
   this.UseProvisioningServer(Item2.JID, OwnerJid); 
   await RuntimeSettings.SetAsync("ProvisioningServer.JID", 
         Item2.JID); 
} 

Here, the OwnerJid contains the JID to the device's owner, if known. If not, it is simply empty.
