This series is really cool. Very informative.

Thank you for sharing. As a token of appreciation i bought the book :)

I have one Quick request though ....Almost all sample applications code here use EF as underneath data source. ..Articles with POCO objects as DATA model will really help where database is NON-SQL Server...

Hi, I'm new to MVVM so excuse the naive question. Is there a reason why the BooksViewModel deals directly with a Book object instead of dealing with BookDetailViewModel object i.e. the Datasource object could just retrurn detail view models insted of books. This way the only class that touches the Book data directly is the detail view model wrapped around it.

Oscar... interesting idea, I'll think about it.

Todd: RelayCommand has a constructor where you can provide a delegate for canExecute logic... however I prefer not to do so, and let the designer decide what he wants to do with the case where a command cannot be invoked... (so I use properties in the viewModel, VisualStates and behaviors to fix this problem)

Hello Zoltan.. great article.. very simple but at the same time very powerful and ready to be used while creating Business Apps..

THANKS

I was also wondering if you would ever add part 4 maybe adding Designer data to see mock data on Blend on VS while designing the app, in the same way John Papa does in his Kung Fu MvvM implementation.

But Zoltan MvvM Implementation is much better (I think) than the complex Kung Fu (too complex to use in the real world ).. so that is why I was wondering
