MEF and MVVM - way to add conventions?

Is there a way to hook into the internals of CompositionContainer?

For example, let's say any time an import is called on a export ending with the word "View" I might want to inject an export ending with "ViewModel" into its DataContext.

Is there a 开发者_高级运维way to do that? I'm trying to avoid code like this in every View:

    [Export("MainView")]
    public partial class MainView : Window
    {
        [ImportingConstructor]
        public MainView([Import("MainViewModel")] dynamic viewModel)
        {
            InitializeComponent();

            DataContext = viewModel;
        }
    }

Would be nice to simplify to just this, and use conventions:

        [Export("MainView")]
        public partial class MainView : Window
        {
            public MainView()
            {
                InitializeComponent();
            }
        }

There are some folks working on this, including the Mef team apparently :) Here is a blog post you might find interesting:

I Guess you are looking for a library or framework which can reduce your effort.

Please have a look at library WPF Application framework. I am using it very well.
