How do you zoom to bounding box using Xamarin Maps? - visual-studio

Question

I have a Xamarin Android map (VS2019) and a number of lat/long points. What I want to do is have the map zoom in (or out), given a set of coordinates that set a bounding box.
I have this code (below) which doesn't seem to do anything. I've read all the documentation which suggests it should work but doesn't. I have checked and the bounding box coordinates are set correctly but the map doesn't do anything.
According to the docs calling LayOut should make it update but it doesn't do anything, no errors, just nothing.
How do I achieve this, any help would be much appreciated.
MyMap.Layout(GetBounds(points));
private Rectangle GetBounds(List<Point> points)
{
var minx = (from x in points select x.X).Min();
var maxx = (from x in points select x.X).Max();
var miny = (from x in points select x.Y).Min();
var maxy = (from x in points select x.Y).Max();
Rectangle rectangle = new Rectangle(minx, miny, maxx - minx, maxy - miny);
return rectangle;
}

Here's what I did
I created a rectangle with the bounds where I need them
Rectangle rectangle = GetBounds(points);
Then I got the rectangle location
Position p1 = new Position(rectangle.X, rectangle.Y);
Position p2 = new Position((rectangle.X + rectangle.Width), (rectangle.Y + rectangle.Height));
... and then got the center point of the rectangle
double x = rectangle.X + (rectangle.Width / 2);
double y = rectangle.Y + (rectangle.Height / 2);
Then called .MoveToRegion using that data, and it works
MyMap.MoveToRegion(
MapSpan.FromCenterAndRadius(
new Xamarin.Forms.Maps.Position(x, y), Distance.BetweenPositions(p1, p2))
);
