✅ Mvvm toolkit - messenger not working? Recive messege not invoked

Hey there im trying to recieve a simple messege using messenger Got this code:

            if (Result == 1) {
                SendToDbSave();
            } 

        }

        [RelayCommand]
        public void SendToDbSave()
        {
            WeakReferenceMessenger.Default.Send(new SaveMessege(Result.ToString()));

        }

            if (Result == 1) {
                SendToDbSave();
            } 

        }

        [RelayCommand]
        public void SendToDbSave()
        {
            WeakReferenceMessenger.Default.Send(new SaveMessege(Result.ToString()));

        }

 public class MainVM : ObservableRecipient, IRecipient<SaveMessege>
    {
        public void Receive(SaveMessege message)
        {
            Console.WriteLine(message.Value);
        }
    }

 public class MainVM : ObservableRecipient, IRecipient<SaveMessege>
    {
        public void Receive(SaveMessege message)
        {
            Console.WriteLine(message.Value);
        }
    }

So why dont i ever go into the recive messege? i do send the messege, but debug point wont go into recive method

I would try registering to receive the message. I don't quite remember when/if it's automatically setup. Make a ctor in MainVM for either:

Messenger.RegisterAll(this);

Messenger.RegisterAll(this);

Messenger.Register<SaveMessege>(this, (r, m) => Receive(m));

Messenger.Register<SaveMessege>(this, (r, m) => Receive(m));

Well i've managed to solve it with Dependency injection, needed to initilaze the class lol forgot
