Implementing MVVM in WPF without using System.Windows.Input.ICommand

Question

I\'m trying to implement a WPF application using MVVM (Model-View-ViewModel) pattern and I\'d like to have the View part in a separate assembly (an EXE) from the Model and ViewM

Off course this is possible. You can create just another level of abstraction. Add you own IMyCommand interface similar or same as ICommand and use that.

Take a look at my current MVVM solution that solves most of the issues you mentioned yet its completely abstracted from platform specific things and can be reused. Also i used no code-behind only binding with DelegateCommands that implement ICommand. Dialog is basically a View - a separate control that has its own ViewModel and it is shown from the ViewModel of the main screen but triggered from the UI via DelagateCommand binding.
