Application crashes when some objc code needs to call PresentViewController method which is overriden in C# code. Please see attached sample app.
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.
Oh, ok. I made a workaround by creating custom view controller in objc and binding it to monotouch.
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 have checked this issue with following builds
X.S 4.2.3(build 59)
I am successfully able to run the attached sample on device. no crash happens.
