binding radiobuttons group to a property in WPF

Declare an enumeration similar to:

enum RadioOptions {Option1, Option2}

XAML:

<RadioButton IsChecked="{Binding SelectedOption, Converter={StaticResource EnumBooleanConverter}, ConverterParameter={x:Static local:RadioOptions.Option1}}"/>
<RadioButton IsChecked="{Binding SelectedOption, Converter={StaticResource EnumBooleanConverter}, ConverterParameter={x:Static local:RadioOptions.Option2}}"/>

Converter class:

public class EnumBooleanConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value.Equals(parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return ((bool)value) ? parameter : Binding.DoNothing;
    }
}
