 > A dependency injection container is ideal for creating view-model instances. If a view-model has dependencies, it will manage the creation and injection of any required services. Just ensure that you register your view-models and any dependencies that they may have in the `CreateMauiApp` method in the `MauiProgram` class.

 ### Dependency lifetime
 
 Depending on the needs of your app, you may need to register dependencies with different lifetimes. The following table lists the main methods you can use to register dependencies, and their registration lifetimes:

 ## Handler disconnection
 
 When implementing a custom control using handlers, every platform handler implementation is required to implement the <xref:Microsoft.Maui.IElementHandler.DisconnectHandler> method, to perform any native view cleanup such as unsubscribing from events. However, prior to .NET MAUI 9, the <xref:Microsoft.Maui.IElementHandler.DisconnectHandler> implementation is intentionally not invoked by .NET MAUI. Instead, you'd have to invoke it yourself when choosing to cleanup a control, such as when navigating backwards in an app.
