Good evening, I try to link the window WPF "MainWindow" with another window WPF that I name it "window". I write this code with MVVMLight Toolkit: ViewModel / MainViewModel.cs public class MainViewModel : ViewModelBase { public ICommand Save { get ; set ; } public MainViewModel() { ave = new RelayCommand(CommandSave); } rivate void CommandSave() { fenetre windows = new fenetre(); windows.Show(); } } does this confirm the MVVM design pattern, or how can I fix it?

i ask how can i relate a new window created in my view with my MainViewModel in using ICommand Save. in addition, i didn't copy the source code in the right way in the first message of post. public class MainViewModel : ViewModelBase { public ICommand Save { get ; set ; } public MainViewModel() { Save = new RelayCommand(CommandSave); } private void CommandSave() { fenetre windows = new fenetre(); windows.Show(); } }
