MAUI memory leak

[phuctran22071992]

I created a simple .NET MAUI project to investigate a memory issue I’m seeing in my main project.

Problem:I registered 3 pages as absolute routes:

//Main

//Main/UserProfile

//Main/Login

Steps to reproduce:

Navigate from MainPage → Login

Navigate from Login → UserProfile

From UserProfile, navigate back → Login

Expected:The UserProfile page should be disposed and removed from memory.

Actual:When I run gcdump and check the heap view, I see the UserProfile page is still in memory.

I’ve already checked the Visual Tree, and the page is not there.

Environment:

Testing on Android device

public partial class AppShell : Shell
{
public AppShell()
{
InitializeRouting();
InitializeComponent();
}

protected override async void OnHandlerChanged()
{
    base.OnHandlerChanged();
    await Shell.Current.GoToAsync("//Main");
}

private static void InitializeRouting()
{
    Routing.RegisterRoute($"//Main/{nameof(LoginPage)}", typeof(LoginPage));
    Routing.RegisterRoute($"//Main/{nameof(UserProfilePage)}", typeof(UserProfilePage));
}

}

<ShellContent
    Title="Home"
    ContentTemplate="{DataTemplate local:MainPage}"
    Route="Main" />

public partial class MainViewModel:ObservableObject
{
public MainViewModel()
{
}

 [RelayCommand]
 private async Task GoToLogin()
 {
    await Shell.Current.GoToAsync($"//Main/{nameof(LoginPage)}");
 }

}

public partial class UserProfileViewModel : ObservableObject
{
public UserProfileViewModel()
{
}

[RelayCommand]
private async Task GoToLogin()
{
    await Shell.Current.GoToAsync($"//Main/{nameof(LoginPage)}");
}

Here is the gcdump heapview when I back to Login Page
