issues with the Geolocator xamarin plugin by James Montemagno
<p>Hello I am working on a app in xamarin forms that needs to take the gps location and combine the latitude and longitude into a url for forcast.io i'm using the Geolocator plugin by James Montemagno and followed the readme but i'm still getting these errors:</p>

<blockquote>

<p>and then here's the radar code:</p>

    public interface MyLocationEventArgs
    {
        double lat { get; set; }
        double lng { get; set; }
    }  

    public partial class RadarHome : ContentPage
    {    
        private readonly CrossGeolocator _locator;

        private double BetaLog;

        public RadarHome()
        {
            MyLocationTracker msi;

            _locator = CrossGeolocator.Current;

            if (_locator.IsGeolocationEnabled == false)

            var position = await _locator.GetPositionAsync(timeoutMilliseconds: 100000);

            BetaLat = position.Latitude; //will work
            BetaLog = position.Longitude; // will work

}

<p>I have the latest Geolocator nuget package installed on all 3 platforms (Froms, iOS, Android) I am using VS2015 update 3 and am still learning xamrarin forms so I'm sorry for asking such a noob question.</p>

<p>Thanks in advance! </p>
