Access Violation when bind to collection

22 Mar 2015, 04:43

Unhandled exception at 0x2BD24F92: Access Violation reading location 0x00000070

I cannot figure out if i am doing this wrong or if its a bug. Property and binding below. I get the access error for every item in the collection when i click the combo box.

    private ObservableCollection<string> _categories = new ObservableCollection<string>();
    public ObservableCollection<string> Categories {
        get { return _categories; }
        set {
            if (_categories != value) {
                _categories = value;
                OnPropertyChanged("Categories");
            }
        }
    }

<ComboBox x:Name="CategoryBox" ItemsSource="{Binding Categories}" />
