CheckedChanged should be listed as an event

[nodoid]

I have a simple form set up with a checkbox control in called chkBox (set up in XAML). It seems that the CheckedChanged event is coming up as a field rather than an event (shows an F in intellisense rather than an E). This means it can't be accessed in XAML or in the code behind using

chkBox.CheckedChanged += ChkBox_Changed;

(or something similar)
