This is a short post about how to implement INotifyPropertyChanged without using any advanced tooling. I have some small UWP applications where I'm using MVVM to separate presentation and logic. Here is how I use INotifyPropertyChanged with a base class for multiple view models.
First, one's introduction to INotifyPropertyChanged comes usually through some existing view model. The interface is used to communicate to the view that some properties in the view model have changed. Take a look at thePropertyChanged event and theNotifyPropertyChanged method (this method is not part of the interface).
