How to handle notification click on Xamarin form ios project

When my Xamarin ios app is in background and I am clicking on the Push notification it is always opening the page i.e in background. Please let me know how I can open another app page on clicking push notifications. when I am clicking on notification public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action completionHandler)
event is called but I am not able to redirect to another app page.

    If the app is in Background state (i.e we have closed all the app pages from the background) then how to navigate to a particular page.

    EASY FIX!!!
    In your delegate.cs and in your mainactivity.cs you are initializing your your App (app.cs) when your can the just save an instance of your app in the mainactivity and delegate classes respectively and then just call any method to navigate or do whatever with the clicked notification.

    Is it possible to open a particular page without Loading the Application in the main activity?
