Method 'UIKit.UIApplication.Main' is obsolete: Use the overload with 'Type' instead of 'String' parameters for type safety

Issue

After upgrade my Xamarin.Forms version to 5.0.0.2244, I'm getting the following warning in Main.cs file inside my iOS project:

Method 'UIKit.UIApplication.Main' is obsolete: Use the overload with 'Type' instead of 'String' parameters for type safety.

This my Main.cs file:

using UIKit;

namespace LindeGctMobileApplication.iOS
{
    public class Application
    {
        private static void Main(string[] args)
        {
            UIApplication.Main(args, null, "AppDelegate"); // << warning
        }
    }
}

What I need to change to remove this warning?

Solution

Class reference through a string is now deprecated. You need to change this line:

UIApplication.Main(args, null, "AppDelegate");

to this:

UIApplication.Main(args, null, typeof(AppDelegate));

In that way, you explicitly inform the type of the class.
