Iteration #4 – Make the application loosely coupledhttp://asp.netWed, 06 Feb 2013 16:45:16 GMTumbracoComments for Iteration #4 – Make the application loosely coupledenComment Posted by ludwigs3rdhttp://asp.net/mvc/tutorials/older-versions/contact-manager/iteration-4-make-the-application-loosely-coupled-csTue, 22 Jun 2010 12:03:42 GMT00000000-0000-0000-000000009181Hi,

Great article! I'm using LINQ to SQL. Would you recommend I return IQueryable<T> instead of IEnumerable<T> in ContactManagerService.ListContacts()?

Thanks.

Listing one has IContactRepository and the class in Listing 2 implements IContactManagerRepository. Troubleshooting exercise for the user, I guess :)

IEnumerable<Contact> ListContacts();

The view needs the contactToEdit as a parameter to provide the model id required by the page.

Nice example of the constructor injection dependency and decorator design patterns here. Great to see how they work with MVC.

Can you explain why wrapping the modelState in this way is using the decorator pattern please? Is it not the adapter pattern?

"

Isn't this example using MEF? What other way using MEF could you completely decouple the classes? Please forgive my ignorance.
