create a background task for network status change

Question

I want to have a background task which gets called which gets triggered when I change from one network to another .Suppose i am connected to a mobile broadband and then switch to wifi , then it should get triggered .When it switches from wifi to mobile broadband , it should trigger 

I have wirtten code as :

            var builder = new BackgroundTaskBuilder();
            builder.Name = name;
            builder.TaskEntryPoint = taskEntryPoint;
            builder.SetTrigger(new SystemTrigger(SystemTriggerType.NetworkStateChange, false));

            if (condition != null)
            {
                builder.AddCondition( new SystemCondition(SystemConditionType.InternetNotAvailable));
            }

            BackgroundTaskRegistration task = builder.Register();

But it works fine when i switch within interface but not  from one interface to another

Answer 1
