No regions at module initializing

In the overriden method on IModule OnInitialized the RegionManager has no regions.

public void OnInitialized(IContainerProvider containerProvider)
{
    var regionManager = containerProvider.Resolve<IRegionManager>();
    regionManager.Regions["ContentRegion"].Add(new ViewA());
 }

When the shell ist created and updates the regions, the visual parent is always null.

When I debug Prism.Wpf, the RegionManager has regions at modul intializing.

I can provide an example, if needed.

OK, this has properly thrown me off. Glad I found this chat.

Can we add a note to the main page as things like this mean the main ReadMe isn’t actually correct as the development isn’t the same as WPF if things like this don’t work as per WPF Prism

Yea, I ported some of the official Prism WPF Samples to Prism.Avalonia. Good practice for Prism and avalonia understanding. =)

With this behavoir some examples / usecases will not work. The example UsingCompositeCommands in the solution https://github.com/EinApfelBaum/Prism.Avalonia.Samples/tree/master/src/11-Commands is one of the use case. In the Module OnInitialized I want to add some Tab Views.
