How do I create instances of my classes in Prism4 MEF?

I have configured container:

public class MyBootstrapper : MefBootstrapper  
{  
    protected override void ConfigureAggregateCatalog()
    {
        AggregateCatalog.Catalogs.Add(xxx.Assembly));
// other assemblies
    }

    protected override void InitializeShell()
    {
        base.InitializeShell();
        Application.Current.MainWindow = (MainWindow)Shell;
        Application.Current.MainWindow.Show();
    }

    protected override DependencyObject CreateShell()
    {
        return Container.GetExportedValue<MainWindow>();
    }
}

How can I create instance of my type T in module? Type T is defined somewhere in assemblies, that are configured by MEF.

I need some like this:

var myType = XXXX.Resolve<T>();

UPD1. MyModule

[ModuleExport(typeof(CatalogModule))]
public class CatalogModule : IModule
{
    private readonly IEventAggregator _event;
    private readonly IUIManager _uiManager;

    [ImportingConstructor]
    public CatalogModule(IEventAggregator @event, IUIManager uiManager)
    开发者_Python百科{
        _event = @event;
        _uiManager = uiManager;
    }

    private void Foo()
    {
        var vm = **How create instance of desired type here?**
    }
}

You do that the same way you got an instance of MainWindow in the CreateShell method override. All you have to do is call Container.GetExportedValue<T>(), which allows you to get an instance directly. If, however, you want to have a type injected, for more loose coupling, you need to have a constructor with and [ImportingConstructor] attribute that depends on that type (or preferably, an Interface), or a property of that type with an [Import] attribute.

Make sure that you have your type exported, by decorating the class with a [Export] attribute, and that the assembly is added to the AggregateCatalog.

Hope this helps ;)
