Csharp 使用.NET DI容器.NET MAUI创建子视图

My Goal is to NOT create dependencies between ViewModels.
I have .NET 7 MAUI project.
The situation is simple.

我有MainPage，并且我使用DI将ViewModel MainPageViewModel链接到它

services.AddSingleton<MainPageViewModel>();

services.AddSingleton<MainPage>(provider =>
{
    return new MainPage()
    {
        BindingContext = provider.GetRequiredService<MainPageViewModel>(),
    };
});

它工作正常，创建了ViewModel，并将其分配给MainPage个AS中的BindingContext个，太棒了.

现在，当我像这样将另一个 children 视图放入MainPage内时

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:MyNamespace"
             x:Class="MyNamespace.MainPage">
    
            <MyNamespace:ChildView />

</ContentPage>

我将它注册到它的ViewModel中，如下所示

services.AddSingleton<ChildViewModel>();

services.AddSingleton<ChildView>(provider =>
{
    return new ChildView()
    {
        BindingContext = provider.GetRequiredService<ChildViewModel>(),
    };
});

The MainPage create the ChildView directly (by calling its parameterless constructor) without consulting the DI Container
This is causing the lack of Binding for the ViewModel.

1. 我不想在MainPageViewModel内创建ChildViewModel并传递它.
2. 在Prism中，这个问题可以使用区域解决，但目前Prism不支持毛伊语
3. MainPage的创造是这样的

<?xml version="1.0" encoding="UTF-8" ?>
<Shell
    x:Class="Trex.Mobile.App.AppShell"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:local="clr-namespace:MyNamespace"
    Shell.FlyoutBehavior="Disabled">

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

</Shell>

and by using this way, the DI container is used.
Can I use something like that for my ChildView or should I change something fundamentally
