Keyed Services Support in MvvmToolkit.Mvvm

How to use keyed services in my Avalonia Application?
I am trying to use the keyed services feature from .net 8, but it is not working for me.

This is what I have in my App.axaml.cs file
```
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using CommunityToolkit.Mvvm.DependencyInjection;

var services = new ServiceCollection();
services.AddKeyedTransient(ServiceList.LocalDB);
Ioc.Default.ConfigureServices(ConfigureServices());
```


This is how I am trying to get the keyed service in some other class
```
Ioc.Default.GetRequiredKeyedService("LocalDB");
```
This is the error that I am getting:

`This service provider doesn't support keyed services.
`

Am I missing something here? or the feature is not implemented yet?

Thank you
