How do you bind a command to a MenuItem (WPF)?

Question

Here is my code from the View.xaml.cs:

private RelayCommand _closeCommand;
public ICommand CloseCommand
{
    get
    {
        if (_closeCommand == null)

Old question, new answer. For me the problem was that GalaSoft.MvvmLight.Command.RelayCommand didn't support closures for the action. RelayCommand stores a weak reference to the action so a closure gets deallocated almost immediately. The action must be a model method or be retained in some other way.
