Visibility converter binding in XAML

I have the following converter:

public class MyConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return Visibility.Hidden;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
...

I'm then using this in XAML as follows:

<Resources>
    <conv:MyConverter x:Key="MyValToVisibilityConverter" />
</Resources>

...

<CheckBox x:Name="MyCheckBox" Content="Should not be visible" 
                Visibility="{Binding ElementName=Visibility, Converter={StaticResource MyValToVisibilityConverter}}" 
...

This compiles and runs, and always shows the checkbox as visible.

You are setting the wrong parameter for the binding.

Right now, the bind target is an element named Visibility, which is most likely an error:

Visibility="{Binding ElementName=Visibility, Converter={...}}"

It should simply be

Visibility="{Binding Converter={...}}"
