Description Ido Shviro 2016-12-18 14:41:41 UTC
In Xamarin.Forms version 2.3 or higher, 
when adding MainPage = new NavigationPage(new ContentPage {  Title = "Hello World"});
this is happening only in iOS.
In version it's not happening!

{System.MissingMethodException: Method 'CGRect..ctor' not found.

Comment 1 Adam Hartley [MSFT] 2017-01-16 12:45:33 UTC
I was not able to reproduce this myself, please can you provide a sample project so that we can debug this issue?
Comment 2 Ido Shviro 2017-05-25 14:05:52 UTC
This has already been resolved.
I think it was resolved by updating Xamarin on visual studio.

this bug hasn't been resolved:


i would appreciate if you could have a look at it.
Thank you.
