Finding the thing registry

We then analyze the set of features presented by each item, or component. If any of them present the namespace defined in XEP-0347 for Thing Registries, we use the JID presented by the component as the address for the registry:

try 
{ 
   Item Item2 = (Item)e2.State; 
 
   if (e2.HasFeature(ThingRegistryClient.NamespaceDiscovery)) 
   { 
         Log.Informational("Thing registry found.", Item2.JID); 
 
         await RuntimeSettings.SetAsync( 
               "ThingRegistry.JID", Item2.JID); 
         await this.RegisterDevice(Item2.JID); 
   } 
} 
catch (Exception ex) 
{ 
   Log.Critical(ex); 
}
