[Docs] Feedback: How to use messaging with MVUX

[ciscisSC]

Both this and the bigger Messaging page includes both using for CommunityToolkit.Mvvm.Messaging and Uno.Extensions.Reactive.Messaging which both has a IMessenger. Which one does the IMessenger actually come from?

I have tried with both and neither works, when I do according to our documentation the page DI the service stops rendering whiteout any errors.

@ciscisSC the IMessenger used by MVUX is directly using CommunityToolkit.Mvvm.Messaging

MVUX does provide some extra extension methods for the IMessenger covered by the docs here

Do you have more details on your example where it isn't working? For a working reference of how the IMessenger should be used can be seen in the Uno Chefs code:

Thanks @kazo0, I had missed that I needed to add IMessenger as a service in the app.xaml.cs file. But I still think the documentation could be clearer since the text talks about both packages and there is not clear which is used (yes only one have correct method for it to work). I checked the ToDoApp sample when and is not used to the practices to brake out the service DI injection into another file which made me miss it.
