Hi I found this tutorial very useful, I want suggest to use the dot conditional operator (?.) in the protected method that wrap event wo explicit checking if handler is null in this way:

this.propertyChange?.Invoke(this, new EventArgsBlaBla());

With expression body function is very concise and elegant :^)

I wrote the blog post before the null conditional operator was available but I've now updated the post, thanks!

Hi there, is it possible to give us an example of how the abstract class NotifyPropertyChanges is used? Thanks In advance.
