What is the correct way to import IEventAggregator from RegisterTypes?

[jamesnet214]

I'm trying to provide the IEventAggregator injected into the ViewModel as a field inside the new instance object. So I got the IEventAggregator via Container.Resolve<IEventAggregator>(). Any problems with this method?

Application

protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
    containerRegistry.RegisterInstance<MyEvent>(new MyEvent(Container.Resolve<IEventAggregator>()));
}

ViewModel

public void MainViewModel(MyEvent myEvent)
{

}

Or should I use the ContainerLocator? Or is it okay if I choose anything because they're all the same?

You don't need to do any of that. Just inject it in the VM ctor

public void MainViewModel(IEventAggregator ea)
{

}

Check out the doc topic: https://prismlibrary.com/docs/event-aggregator.html
