Tracking my Model in Watch Window

Question

I was wondering what is best practice for instantiating a Model in your ViewModel class for purposes of adding it to the watch window so that you can see your Model Properties change while the application runs in debug mode. Thanks !!!!

Hello,

Do you implement the INotifyPropertyChanged in your Model?

If so, you can add Console.WriteLine(value); in get/set method of properties. When you debug your application, you can see the value changes of properties of Model in output Window.

   public class MyModel : INotifyPropertyChanged  
   {  
       double hue;  
         
      public event PropertyChangedEventHandler PropertyChanged;  
     
      public double Hue  
       {  
           set  
           {  
               if (hue != value)  
               {  
                   hue = value;  
                   OnPropertyChanged("Hue");  
                   Console.WriteLine("Hue:   " + value);  
               }  
           }  
           get  
           {  
               return hue;  
           }  
       }  
       protected virtual void OnPropertyChanged(string propertyName)  
       {  
           PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));  
       }  
   }
