Get notified when static property changes in wpf

Question

Here microsoft described that in wpf 4.5 we can use INotifypropertyChanged for static properties as well. So I tried to do that.

Here is the code:

pu         


        

Answer 1

Unless anything uses the sender parameter, it won't matter. Logically it would make sense to use the type:

handler(typeof(TypeDeclaringEvent), new PropertyChangedEventArgs(PropertyName));

EDIT: Note that in the document you referred to, it states:

The static event can use either of the following signatures.

   public static event EventHandler MyPropertyChanged;
   public static event EventHandler StaticPropertyChanged;

Your event doesn't comply with these, which could be an issue.
