Answer 1

Simplified version of ragunathan's answer.

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) =>
    Convert(value);

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) =>
    Convert(value);

private object Convert(object value) => 
    value is bool ? !(bool)value : value;
