Xamarin - basic map creation + current location + set a pin + zoom level

gistfile1.txt

// put a map into the View
var map = new MKMapView (UIScreen.MainScreen.Bounds);
View = map;

//allows user location to be shown on a map
map.ShowsUserLocation = true;

//get my current geo-location lat/long coordinates
var myCoord = map.UserLocation.Coordinate;
Console.WriteLine ("lat {0}, long {1}", myCoord.Latitude, myCoord.Longitude);

//puts an annotation on the point of interest geo-coordinates
map.AddAnnotation (new MKPointAnnotation () {
	Title = "My annotation",
	Subtitle = "the subtitle",
	Coordinate = new CLLocationCoordinate2D(myCoord.Latitude,myCoord.Longitude)
});

//centers the map to designated geo-coordinates
map.CenterCoordinate = new CLLocationCoordinate2D(myCoord.Latitude,myCoord.Longitude);

//define co-ordinates and a "span" so you can zoom in to the desired level on the map
var coords = new CLLocationCoordinate2D (myCoord.Latitude,myCoord.Longitude);
MKCoordinateSpan span = new MKCoordinateSpan(0.06,0.06);

//tell the map to use the co-ordinates and span
map.Region = new MKCoordinateRegion(coords, span);
