Xamarin Forms - how to add background image to a content page

My suggestion is to put images to folder:

for Android Resources/drawable

for iOS Resources

public class MainPage : ContentPage
{
    List<string> objEmpCollections = new List<string>();
    public MainPage()
    {
        this.Title = "V V I P's";
        //this.BackgroundColor = Color.Maroon;
        this.BackgroundImage = "EmpMgmtPCL.Images.NPO-Events-bg.png";
    }
}
