Merhaba arkadaslar;

microsoft.Toolkit.Mvvm paketi ile Dictionary değiştiğinde PropertyChanged eventini fırlatmıyor. Hiç bir şekilde View'i güncellemeyi başaramadım. Yardımcı olursanız sevinirim.

viewModel

  [ObservableProperty]
  private string programName;

  [ObservableProperty]
  private string programValue;

  [ObservableProperty]
  private Dictionary<string, string> monday = new Dictionary<string, string>();


   [ICommand]
   public void AddProgram ()
   {
            Monday.Add(ProgramName, ProgramValue);
            SetProperty<Dictionary<string, string>>(ref monday, Monday); 
            ProgramName = null;
            ProgramValue = null;

     }
