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

Answer 1

WinForms doesn't have the rich data binding and commands infrastructure needed to use a MVVM style view model.

Just like you can't reuse a web application MVC controllers in a client application (at least not without creating mountains of wrappers and adapters that in the end just make it harder to write and debug code without providing any value to the customer) you can't reuse a WPF MVVM in a WinForms application.

I haven't used GTK# on a real project so I have no idea what it can or can't do but I suspect MVVM isn't the optimal approach for GTK# anyway.

Try to move as much of the behavior of the application into the model, have a view model that only exposes data from the model and calls into the model based on commands with no logic in the view model.

Then for WinForms just remove the view model and call the model from the UI directly, or create another intermediate layer that is based on WinForms more limited data binding support.

Repeat for GTK# or write MVC controllers and views to give the model a web front-end.

Don't try to force one technology into a usage pattern that is optimized for another, don't write your own commands infrastructure from scratch (I've done it before, not my most productive choice), use the best tools for each technology.
