To add a mini map to a map, do the following.

// In the Form's constructor.
object data = LoadData(@"..\..\Data\Ships.xml");

// Create a mini map and data for it.
MiniMap miniMap = new MiniMap();
miniMap.Alignment = MiniMapAlignment.BottomLeft;
miniMap.Layers.AddRange(new MiniMapLayerBase[] {
    new MiniMapImageTilesLayer() {
        DataProvider = new BingMapDataProvider() {
            BingKey = "YOUR_BING_MAPS_KEY_HERE"
        }
    },
    new MiniMapVectorItemsLayer() {
        Data = CreateMiniMapAdapter(data)
    }
});
map.MiniMap = miniMap;


// Creates an adapter for the map's vector layer.
private IMapDataAdapter CreateAdapter(object source) {
    ListSourceDataAdapter adapter = new ListSourceDataAdapter();

    adapter.DataSource = source;

    adapter.Mappings.Latitude = "Latitude";
    adapter.Mappings.Longitude = "Longitude";

    adapter.AttributeMappings.Add(new MapItemAttributeMapping() { Member = "Name", Name = "Name" });
    adapter.AttributeMappings.Add(new MapItemAttributeMapping() { Member = "Year", Name = "Year" });
    adapter.AttributeMappings.Add(new MapItemAttributeMapping() { Member = "Description", Name = "Description" });

    return adapter;
}

// Loads data from a XML file.
private List<ShipwreckData> LoadData(string path) {
    return XDocument.Load(path).Element("Ships").Elements("Ship")
        .Select(e => new ShipwreckData(
            year: Convert.ToInt32(e.Element("Year").Value, CultureInfo.InvariantCulture),
            name: e.Element("Name").Value,
            description: e.Element("Description").Value,
            latitude: Convert.ToDouble(e.Element("Latitude").Value, CultureInfo.InvariantCulture),
            longitude: Convert.ToDouble(e.Element("Longitude").Value, CultureInfo.InvariantCulture)
        ))
        .ToList();
}

public class ShipwreckData {
    public int Year { get; }
    public string Name { get; }
    public string Description { get; }
    public double Latitude { get; }
    public double Longitude { get; }
