Am having an issue with binding, but I first searched with several questions on this, but no luck, below is the error am getting :

> 
> Error: Position 18:36. No property, bindable property, or event found
>  for 'Lat', or mismatching type between value and property
>

Below is my **xaml** file :

```
<controls:MapView x:Name="map" VerticalOptions="FillAndExpand">
            <controls:MapView.Center>
                <controls:Position Lat="{Binding latitude}" Long="{Binding longitude}" />
            </controls:MapView.Center>
        </controls:MapView>

```

Then the **`c#`** code is as below :

```
public partial class DisplayMap : ContentPage
    {

        private double latitude { get; } 
        private double longitude { get; } 

        public DisplayMap()
        {

            InitializeComponent();

            this.latitude = 0.3476;
            this.longitude = 32.5825;

            BindingContext = this;

        }

```
