Is it possible to build a Visibility Converter in Xamarin?

So far I have:

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using Xamarin.Forms;

namespace MyProject
{
    class BoolToVisibilityConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return (bool)value ? Visibility.Visible : Visibility.Collapsed;
        }

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

The usual Visibility Converter but I get the error: "The name 'Visibility' does not exist in the current context" is it possible to build a Bool to visibility converter in Xamarin?
