MEF and MEFedMVVM

Oct 12, 2010 at 4:52 PM

Hi,

I am working on a project using MEF and MEFedMVVM, MEF is used to load a number of .xap files as required, and MEFedMVVM is used to locate the ViewModels withing the dynamically loaded .xap files that contain the XAML and view models. The problem I am having is that I need to import a menu service into the ViewModels from the main module. The menu service is created as shared, but I get a new instance created for all the dynamically loaded view models. So one instance in the main module and a second instance for all the view models. Is there a way can get the instance from the main module? What I think is happening is that MEF is creating the first instance, and MEFedMVVM is creating the second.

Any help with this would be most appreciated.

Regards,

you should be using always MEFedMVVM so that there is one composition container!
