Test Project

Overriding the method
>public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations(UIApplication application, UIWindow forWindow)

in the AppDelegate causes the app to freeze when running on device after the full screen video player is dismissed.

Steps to reproduce:
1. Load and run the attached test project to a device (issue does not occur on simulator)
2. Press the Play Movie button
3. Press Done to dismiss the video player.
4. Press the Play Movie button

Expected result: movie will play again.
Actual result: app is frozen.

5. Open the AppDelegate.cs file and comment out the GetSupportedInterfaceOrientations method. 
6. repeat steps 1 through 4

Expected result: movie will play again
Actual result: as expected. 

I tested this with a simple Xcode project as well and this issue did _not_ occur in a fully native Obj-C app (test project attached as well)

Note that this only seems to occur overriding that method in the AppDelegate class. Overriding 
public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations();
in a view controller class does not seem to cause this issue.

This is technically a dup of bug #13966, however I'm not sure if it's a regression or if #13966 was never properly fixed.

In any case it should be fixed now.

Pending backport to monotouch-7.4.0-branch.

QA: please add the test project from the original description to the test suite (I've not been able to create a unit test for it).

I have checked this issue and run the attached application on device (iPhone 4s iOS8) and I am able to run application again and again after clicking on Done button i.e. application is not frozen when we restart video.

Hence closing this issue.
