Creating a new instance of an object each time method is called

Question

Messenger.Default.Register(this, message =>
{
    var adventurerWindowVM = SimpleIoc.Default.GetInstance();
           


        

Answer 1

I think you are trying to use the same instance of your ViewModel with multiple views. So the views will obviously overwrite each others viewmodel contents.

What if you do this;

        Messenger.Default.Register(this, message =>
    {
        var adventurerWindowVM = new AdventurerViewModel();
        adventurerWindowVM.Adv = message.Argument;
        var adventurerWindow = new AdventurerView() 
        {
            DataContext = adventurerWindowVM
        };
        adventurerWindow.Show();
    });
