Comment 1 Matthew Leibowitz 2014-09-17 07:52:55 UTC
This is nicely formatted one:

Comment 2 Sebastien Pouliot 2014-09-17 09:43:51 UTC
That looks like a miscompiled MonoTouch.Dialog (missing or, more likely, broken resource).

Failure happens when trying to execute this line (from the static ctor).

		static UIImage arrow = Util.FromResource (null, "arrow.png");
Comment 3 Sebastien Pouliot 2014-09-17 10:24:22 UTC
The same code (as comment #1) works fine with me. Can you tell us exactly which versions* of the software you're using ?

Also the version of iOS (sim or devices) along with the type of device could be helpful (this is not the type of bugs that is generally related to this but I rather try to replicate this as closely as possible).

* The easiest way to get exact version information is to use the "Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" button and copy/paste the version informations (you can use the "Copy Information" button).

Comment 5 Matthew Leibowitz 2014-09-17 11:23:00 UTC
It works fine in classic apps
Comment 6 Sebastien Pouliot 2014-09-17 11:48:56 UTC
ah, I need to start adding classic/unified to my question list (and better check the stack trace, UIKit.UIApplication.Main was an hint).
Comment 7 Sebastien Pouliot 2014-09-17 15:26:59 UTC
This works fine (unified) on master, I'll confirm with 8.2 (which will be alpha pretty soon) but I think it's already fixed.
Comment 8 Sebastien Pouliot 2014-09-17 16:24:15 UTC
Got it, it only happens on 64 (not 32) bits.
Comment 9 Sebastien Pouliot 2014-09-17 16:55:19 UTC
Fixed in monotouch/master c8eda0180aedfc7111aee9ec02a4521abe841bfe
and monotouch-8.2.0-branch 973f8d4c74f6248e067fef5b387c3b82b7545fe5
Comment 10 Danish Akhtar 2014-10-01 11:31:02 UTC
I am trying to verify this issue but not sure about the steps. Could you please provide test case or steps? so, we can verify this issue.

Comment 11 GouriKumari 2014-10-02 12:32:54 UTC
