The web browser being System.Windows.Forms.WebBrowser.
So I know I can run code constantly to check if it has changed but this seems very inefficient. I have looked into INotifyPropertyChanged but don't know how I would implement it and am not sure it would work with a predefined system property. I have also looked into Fody/PropertyChanged but I don't believe it would inject into System properties. Any help is appreciated. Thanks so much.
Additionally, here is the reason I need this. I am using the web browser to do OAuth 2.0 authorization. I want to be able to read the url only when it changes to then get the auth token. Thanks again.
