This can be duplicate with maccore/master too
Comment 2 Sebastien Pouliot 2015-09-24 09:31:57 UTC
The handler signature is incorrect. It probably changed during the betas and this handlers signature changes are not something our API tests catch.
Comment 3 Sebastien Pouliot 2015-09-24 09:53:55 UTC
Fixed in maccore/master dfa21c91d2c301202368bcc0bba3637fe8c6f2ef

I verified this issue with Xamarin.iOS master Xamarin.iOS
Version: (Enterprise Edition)
Hash: dfa21c9.

Test Results:
I could reproduce the issue with the current stable
StackTrace: https://gist.github.com/GouriKumari/d3333074faaa3f59e2c4

With fix:
I couldn't reproduce the invalid cast exception. But, continuously got "2015-09-24 16:42:33.063 ReplayKitCrash[1666:1375455] -[UIWindow endDisablingInterfaceAutorotationAnimated:] called on <UIWindow: 0x15cd79790; frame = (0 0; 320 568); autoresize = W+H; gestureRecognizers = <NSArray: 0x15cd7ab30>; layer = <UIWindowLayer: 0x15cd791f0>> without matching -beginDisablingInterfaceAutorotation. Ignoring."

Comment 5 Sebastien Pouliot 2015-09-24 17:40:36 UTC
I did not see those messages (but I did not really look for any either) but they are not related to the fix.

Those looks like a sample issue (they are not API that XI calls by itself),
Comment 6 Philippe Rollin 2015-10-05 15:15:04 UTC
The issue seem to be fixed with the latest stable release on OSX but remains when using Visual Studio. It seems that the signature of RPScreenRecorder.StopRecording() is still missing a parameter when compiling using Xamarin for Visual Studio. Below is the version information of my setup.

Comment 7 Sebastien Pouliot 2015-10-05 15:20:42 UTC
@Philippe XVS 3.11.1450 should be the matching version and available (like XI's on the beta channel.
Comment 8 Philippe Rollin 2015-10-05 16:32:10 UTC
I tried the beta channel and I am getting the same issue (works in Xamarin Studio on OSX)
Comment 9 Sebastien Pouliot 2015-10-05 16:36:48 UTC
@Joe any clue why ?
