Assuming you are using version 2.0.1?

I think you will need to show me a little more code.

That said, let me ask this though:

Are you implementing the interfaces? This is important.

Here's the source: INavigatedAware or INavigatedAwareAsync

It's easiest if you use the ViewModelBase class, but that's not required.

Here's a sample view-model:

public class MyViewModel : INavigationAware
{
    public void OnNavigatedFrom(INavigationParameters parameters)
    {
        throw new NotImplementedException();
    }

    public void OnNavigatedTo(INavigationParameters parameters)
    {
        throw new NotImplementedException();
    }

    public void OnNavigatingTo(INavigationParameters parameters)
    {
        throw new NotImplementedException();
    }
}

The framework only knows to call these methods if it determines the interfaces are present.

If you are interested, here's where the framework actually does that.
