Xamarin.Forms MainPage

I have doubt regarding Xamarin.Forms MainPage property in terms of memory leak.

Say for instance I started my application with LoginPage

App.cs

MainPage = new LoginPage();

After successful login, LoginPage.cs

MainPage = new NavigationPage(new HomePage());

What happens with LoginPage instance? Is that remains in memory until garbage collector collects it, or it gets destructed?

the GC will handle it, unless you choose to explicitly dispose of it - Jason
Its problem then, because Pages may have images/large contents.. which is not good to have loaded in RAM. Don't we have option like finish current page and start new, same as Android!! - Afzal Ali
How is it a problem? The garbage collector will clean it up, and if you really want it to be cleaned up immediately, implement IDisposable on your page and do a simple check and clean it up properly. Alternatively you can force the garbage collector to run, but that's not a recommended practice. - Bill Reiss
I highly recommend brushing up on the Xamarin GC. developer.xamarin.com/guides/android/advanced_topics/…. - Joshua Poling

I suggest uninstall the existing app in the emulator and redeploy the application again
