I am creating custom control for Xamarin.Forms. And i have faced the issue similar to this question,

I have checked this issue and unable to reproduce it.

I have tried following steps to reproduce it.
1.Create a Xamarin form application.
2.Add a class(Mypage.cs)
3.Call Mypage.cs in App.cs and Did some code in it using custom cotrol.
4.Run the application

I observed that application successfully deployed on ios simulator.

 public  class Mypage :ContentPage

     public Mypage()

         Content = new StackLayout
             Children = {
        new Label {
          Text = "Hello, Custom Renderer !",
        new Entry {
          Text = "In Shared Code",
             VerticalOptions = LayoutOptions.CenterAndExpand,
             HorizontalOptions = LayoutOptions.CenterAndExpand,


Let me know if I missed anything to reproduce it.
