Esse método tem o mesmo efeito que definir a Active propriedade como true.

var blueView = new ContentView(UIColor.Blue);
view.AddSubview(blueView);

blueView.TranslatesAutoresizingMaskIntoConstraints = false;
var blueConstraints = new []
{ 
    blueView.LeadingAnchor.ConstraintEqualTo(greenView.LeadingAnchor),
    blueView.TrailingAnchor.ConstraintEqualTo(greenView.TrailingAnchor),
    blueView.TopAnchor.ConstraintEqualTo(greenView.BottomAnchor, 10.0f),
