Question

When using unity you can import the container in the constructor of a view moder per say.

But how would I do import a MEF container into a view model to resolve instances?

Thanks

Generally, it is not a great idea to be passing round the container, as you end up using it as more of a service-location mechanism, but should you wish to do so, you would need to manually export the container, e.g.:

var container = new CompositionContainer(catalog);
container.ComposeExportedValue(container);

This will enable you to import it:

[Import]
public CompositionContainer Container { get; set; }

Or:

[ImportingConstructor]
public MyClass(CompositionContainer container) { }
