I guess this signature is wrong.
The static member DefaultQueue of NSNotificationQueue class returns it as an NSObject.
Surely I confirmed that it works as an proper instance of NSNotificationQueue like following code snippet;

var notification = NSNotification.FromName ("ANotificationWhichPostWhenIdle", null);
var que = new NSNotificationQueue (NSNotificationQueue.DefaultQueue.Handle);
que.EnqueueNotification (notification, NSPostingStyle.PostWhenIdle);

Or Is there any restriction or recommendation that it should not be used or somewhat.
Thank you for your help.

Yes, I tracked the original commit (3 years old) and it's a binding mistake. It should return a `NSNotificationQueue`. 

I'll fix this for future releases, but you can safely cast it for `NSNotificationQueue` in existing applications.

I have checked issue on following builds:

Mac OS X 10.7.5
Xamarin.iOS: (Trial Edition)
Xamarin Studio: 4.2.3 (build 60)
Build Information
Release ID: 402030060
Git revision: 30c4afc300c2a39ec5300851357ce02e49dd217e
Build date: 2014-03-05 22:09:33+0000
Xamarin addins: f8a9589b57c2bfab2ccd73c880e7ad81e3ecf044

To verify this issue I have check the definition of static member "DefaultQueue" of "NSNotificationQueue" class in assembly browser and I observed that the static property "DefaultQueue" doesn't return "NSObject" now it's returning an object of "NSNotificationQueue" class

This issue is working fine. Hence, I am closing this issue.
