I'm simplifying the example here and leaving out NotifyPropertyChanged, etc., but in the r...

I'm using MVVM Light toolkit (which I love). I currently have messaging in place for some interaction originating from the ViewModel and intended for consumption by the View.

I've used PureMVC before with AS3, and am playing around with WP7 so thought it would make sense to try the C# port (http://trac.puremvc.org/PureMVC_CSharp/) The problem I'm having is that the samples (Login/Employee Admin) don't use the NavigationService to change states within the application - they simply hide/show controls when need...
I'm building a WPF application which is based on the MVVM pattern. Later on we are going to build a Silverlight application of the same type, and also a Web application. I want to use my ViewModels in all three UI:s, so my idea was to move the vm:s to a class library, but then I lost my ICommands, is there an easy way to get around t...

New widgets will be created and added to the application using MEF and they should be able to import some controls from the core application. So how to export those controls prop...
Hi there I would like to design a light "members listing/editing" app in one and only window. My guess was that the best and simplest way to achieve this would be to have the "listing" part (mostly a datagridview and some search stuff) on a panel, and the "editing" (new member or modify member) on another, each panel hiding the other d...
