Xamarin.Forms MessagingCenter Unsubscribing
Example
When you no longer need to receive messages, you can simply unsubscribe. You can do it like this:
MessagingCenter.Unsubscribe<MainPage> (this, "Hi");
When you are supplying arguments, you have to unsubscribe from the complete signature, like this:
MessagingCenter.Unsubscribe<MainPage, string> (this, "Hi");
