<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />

iOS (info.plist)

<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs to use your location</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs to use your location</string>
<key>MGLMapboxAccessToken</key>

Your XAML

<local:MapView 
    x:Name="map" 
    VerticalOptions="FillAndExpand" 
    MapStyle="{Binding CurrentMapStyle}" 
    ZoomLevel="{Binding ZoomLevel}"
/>

Your code behind

map.DidTapOnMapCommand = new Command<Tuple<Position, Point>>((Tuple<Position, Point> obj) =>
{
    var features = map.GetFeaturesAroundPoint.Invoke(obj.Item2, 6, null);
    var filtered = features.Where((arg) => arg.Attributes != null);
    foreach (IFeature feat in filtered) {
        var str = JsonConvert.SerializeObject(feat);
        System.Diagnostics.Debug.WriteLine(str);
    }

});
map.DidFinishLoadingStyleCommand = new Command<MapStyle>((obj) =>
{
    map.ResetPositionFunc.Execute(null);
    foreach (Layer layer in obj.OriginalLayers)
    {
        System.Diagnostics.Debug.WriteLine(layer.Id);
    }

});
map.ZoomLevel = Device.RuntimePlatform == Device.Android ? 4 : 10;

Detailed documentation is coming soon.

Using Vector Tiles (WMTS)

For example, using a GeoServer WMTS url, and having a workspace named "Ski" and a layer named "planet_osm_line".

After DidFinishLoadingStyle :

var TILESET_URL = "http://localhost:8080/geoserver/gwc/service/wmts?REQUEST=GetTile&SERVICE=WMTS&VERSION=1.0.0&LAYER=Ski:planet_osm_line&STYLE=&TILEMATRIX=EPSG:900913:{z}&TILEMATRIXSET=EPSG:900913&FORMAT=application/vnd.mapbox-vector-tile&TILECOL={x}&TILEROW={y}";

var skiTiles = new TileSet("1.0.0", SOURCE_URL)
{
    MinZoom = 12f,
    MaxZoom = 22f
};

var tileSourceOptions = new TileSourceOptions();
tileSourceOptions.MinimumZoomLevel = 12;
tileSourceOptions.MaximumZoomLevel = 22;

VectorSource vectorSource = new VectorSource("vector-source", skiTiles, tileSourceOptions);

map.Functions.AddSource(vectorSource);

var myLayer = new LineLayer("tile-data", "vector-source")
{
    LineColor = Expression.Color(Color.FromHex("#F13C6E")),
    LineWidth = Expression.Literal(4.0f),
    LineCap = Expression.Literal("round"),
    LineJoin = Expression.Literal("round"),
    SourceLayer = "planet_osm_line"
};
map.Functions.AddLayer(myLayer);
