Sample app.

Application crashes when some objc code needs to call PresentViewController method which is overriden in C# code. Please see attached sample app.
Comment 1 Rolf Bjarne Kvinge [MSFT] 2012-07-23 08:58:03 UTC
This is because we currently do not support conversion from ObjC blocks to C# delegates, only the reverse.

This is also related to bug #4781.
Comment 2 Michal 2012-07-25 07:45:19 UTC
Oh, ok. I made a workaround by creating custom view controller in objc and binding it to monotouch.

thanks.

This bug was targeted for a past milestone, moving to the next non-hotfix active milestone.

This was fixed around XI 7 IIRC. The sample app works fine now.

I am successfully able to run the attached sample on device. no crash happens.
