I am attempting to implement a MVVM WPF application in Python.Net.

The ViewModel class needs to implement the INotifyPropertyChanged interface.

class ViewModel(System.ComponentModel.INotifyPropertyChanged):

def __init__(self):

pass

vm = ViewModel()

gives exception:

"TypeError: interface takes exactly one argument"

I am not sure what is the reason.

I remember a post last year saying the the interface inheritance is implemented in a development brand and not integrated into main branch. not sure if it is the reason.

I am using python 2.1.0.dev1.

thanks
